The phosphanylthiol PPh(2-C6H4SH)2 reacts with the NiII and PdII complexes [MCl2L2] in the presence of NaOEt to give the mononuclear derivatives [M{PPh(C6H4S)2}L] [M = Ni, L = PPh3 (1), PPh2Me (2); M = Pd, L = PPh3 (3)]. The analogous reaction starting with complexes containing bidentate ligands [MX2(L-L)] produces different results depending on the ligand used. The complexes [M{PPh(C6H4S)2}(dppm)] [M = Ni (4), Pd (5)], with an unligated phosphorus atom in the diphosphane are obtained with bis(diphenylphosphanyl)methane (dppm), while the dinuclear complexes [M2(mu-dppe){PPh(C6H4S)2}] [M = Ni (6), Pd (7)] are isolated in the case of 1,2-bis(diphenylphosphanyl)-ethane (dppe). With 1,10-phenanthroline (phen), the complexes [M{PPh(C6H4S)2}(phen)] [M = Ni (8), Pd (9)] are obtained, but when 2,2?-bipyridine is used the dinuclear compounds [M{PPh(C6H4S)2}]2 [M = Ni (10), Pd (11)] are isolated instead. Complexes 10 and 11, which can be obtained starting from NiCl2 or [PdCl2(NCPh)2] respectively, afford complexes 1-7 when treated with the respective phosphanes in the appropriate stoichiometries. The structures of 2, 7 and 10 have been confirmed by X-ray analysis.

The thermal analysis of the complexes [Ni(phen)3][PdCl4]·3H2O and [Ni(bipy)3][PdCl4]·212-H 2O revealed, after the elimination of the molecules of water, the reciprocal migration of the ligands between the coordination spheres of the two metal ions. This solid-state reaction leads to mixtures of two neutral complexes: Ni(AA)2Cl2 and Pd(AA)Cl2 (AA=phenanthroline or bipyridine). In both cases, the migration was found to be exothermic. The bis-chelated nickel complexes, Ni(AA)2Cl2, were extracted in ethanol and separated from Pd(AA)Cl2. Subsequent addition of an hydrochloric acid solution of ZnCl2 to the ethanol solution containing Ni(phen)2Cl2 led to the formation of [Ni(phen)2(H2O)2][ZnCl 4]·H2O which was studied by X-ray diffraction methods. The Ni-N bond distances vary from 2.078(3) to 2.089(4)A, while the cis Ni-O distances are 2.057(3) and 2.073(3) A. The crystal structure of Ni(bipy)2Cl2·2H2O· 12-CH3CN was also determined. The compound is the cis isomer, with the Ni atom located on a 2-fold axis. The Ni-N bonds distances are 2.084(3) and 2.094(2) A, while the Ni-Cl bonds distances are 2.428(1) A. The compound crystallizes with two water molecules situated in the lattice and 12- molecule of acetonitrile located on a 2-fold axis. The two crystals are stabilized by hydrogen bonds involving the water molecules.

Syntheses and crystal structure determinations of [Pd(bpy)([9]aneS3)][PF6]2 (bpy = 2,2′-bipyridine; [9]aneS3 = 1,4,7-trithiacyclononane) and [Pt(phen)([9]aneS3)][PF6]2 (phen = 1,10-phenanthroline) are reported. The Pd compound (C16H20N2S3PdP2F12) crystallizes in triclinic space group P1- (No. 2), with a = 10.376(3) A, b = 10.810(2) A, c = 10.907(2) A, alpha = 84.25(1)°, beta = 87.25(2)°, gamma = 84.89(2)°, Dc = 2.009 g cm**-3, and Z = 2; the Pt compound (C18H20N2S3PtP2F12) crystallizes in orthorhombic space group Pbca (No. 61), with a = 15.422(3) A, b = 10.618(2) A, c = 31.335(6) A, Dc = 2.189 g cm**-3, and Z = 8. Each structure features a five-coordinate metal center in a distorted square-pyramidal geometry. Two diimine nitrogensand two of the S-donors of [9]aneS3 are bound in the square plane, (M-N2.06-2.07 A; M-S 2.27-2.29 A), whereas the third sulfur of the thia crown ether occupies the apical position (Pd-S 2.81 A; Pt-S 2.82 A). The room-temperature (1)H NMR solution spectrum of each complex shows an AA’BB’ pattern in the methylene region. The NMR spectral properties of [Pt(phen)([9]aneS3)][PF6]2 between room temperature and -91°C in acetone-d6 solution are interpreted in terms of relatively rapid intracomplex rearrangements (DeltaG(.++.) .apprx. 38 kJ mol**-1; Tc= -80°C) similar to the nuclear motions associated with the formation and decay of the transition state in a Pt(II) associative substitution reaction.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Recommanded Product: 14871-92-2. Introducing a new discovery about 14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II)

A number of platinum(II) and palladium(II) complexes containing the monoanion of isatin (2,3-dihydroindole-2,3-dione, Hisat) have been synthesized by reaction of the metal halide complex with isatin, in the presence of triethylamine. The complexes have been characterised by NMR and IR spectroscopies and elemental analysis. A single-crystal X-ray diffraction study has been carried out on cis-[Pt(isat)2(PPh3)2], which shows two cis-isat ligands with their dicarbonyl functions pointing in opposite directions. Electrospray mass spectrometry was also used for characterisation; the complexes show a strong tendency to form aggregate ions with ammonium ions, and both mono- and di-cationic species are observed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 14871-92-2, you can also check out more blogs about14871-92-2

PdCl2(bipy) complex (bipy = 2,2?-bipyrydine) efficiently catalyzes the vinylation of aryl halides. The activity of this catalyst for the Heck reactionwas demonstrated for a variety of aryl halides and olefins in the presence of different organic and inorganic bases. The catalyst is stable under the reaction conditions and no degradation was observed. The kinetics of the Heck coupling of styrene with iodobenzene using the PdCl2(bipy) complex with potassium acetate as a base was studied over a temperature range of 393-413 K in 2-nitro-2-methyl-1-propanol medium. An empirical rate model has been proposed to fit the observed data and is found to be in good agreement with experimental results. The activation energy of the reactionwas found to be 98.70 kJ/mol.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 14871-92-2, name is (2,2′-Bipyridine)dichloropalladium(II), introducing its new discovery.

Heterodinuclear complexes, syn-[MPt(mu-pyt)2(bpy) 2]n+ (syn-[MPt], M = Pd2+, Au3+, Hpyt = pyridine-2-thiol, bpy = 2,2?-bipyridine), were synthesized as a selective geometrical isomer by stepwise complexation. X-ray analyses of the hexafluorophosphate salts of these complexes proved their dinuclear structures with short M…Pt distances (2.9084(4) A for syn-[PdPt] and 2.9071(4) A for syn-[AuPt]), similar to the homodinuclear complex (2.9292(2) A for syn-[PtPt]). In the syn-[PdPt] crystal, two dinuclear motifs are arranged closely in a head-to-head manner with a short Pt…Pt distance (3.3757(3) A), forming a dimer-of-dimer structure as in the case of syn-[PtPt], whereas the corresponding crystal of syn-[AuPt] has a discrete arrangement of the dinuclear motifs. By the isomerisation of syn-[PdPt], anti-[PdPt] with equivalent environments of the Pd2+ and Pt 2+ ions was also obtained successfully. Syn-[PdPt](PF 6)2 exhibits vapochromic behaviour based on the absorption/desorption of CH3CN vapour, similar to that observed for syn-[PtPt](PF6)2. The reversible structural transformations induced by the uptake and release of CH3CN molecules were investigated by powder and single-crystal X-ray diffraction studies. These revealed that the vapochromic behaviour was based on the interconversion between two phases, the dimer-of-dimer structure with a short Pt…Pt distance and a pi-pi stacked arrangement with no Pt…Pt intermolecular interaction. The introduction of the heterometal ions enabled control of the colour region: orange ? red for syn-[PdPt] vs. light red ? dark red for syn-[PtPt], reflecting the weaker metal-metal interaction between Pd 2+ and Pt2+ ions in the dinuclear motif. In addition, these complexes were found to exhibit mechanochromic behaviour based on a crystal-to-amorphous transformation upon grinding, and the reconstruction of the crystal structures by vapour sorption.
