2,6-Bis(benzimidazol-2-yl)pyridine (L) ligand and complexes [M(L)Cl2] and [Fe(L)2](ClO4)2 (M = Zn, Cd, Hg) have been synthesized. The geometries of the [M(L)Cl2] complexes were derived from theoretical calculation in DGauss/DFT level (DZVP basis set) on CACHE. The central M(II) ion is penta-coordinated and surrounded by N3Cl2 environment, adopting a distorted trigonal bipyramidal geometry. The ligand is tridentate, via three nitrogen atoms to metal centre and two chloride ions lie on each side of the distorted benzimidazole ring. In the [Fe(L)2](ClO4)2 complex, the central Fe(II) ion is surrounded by two (3N) units, adopting a octahedral geometry. The elemental analysis, molecular conductivity, FT-Raman, FT-IR (mid-, far-IR), 1H, and 13C NMR were reported. The antimicrobial activities of the free ligand, its hydrochloride salt, and the complexes were evaluated using the disk diffusion method in dimethyl sulfoxide (DMSO) as well as the minimal inhibitory concentration (MIC) dilution method, against 10 bacteria and the results compared with that for gentamycin. Antifungal activities were reported for Candida albicans, Kluyveromyces fragilis, Rhodotorula rubra, Debaryomyces hansenii, Hanseniaspora guilliermondii, and the results were referenced against nystatin, ketaconazole, and clotrimazole antifungal agents. In most cases, the compounds tested showed broad-spectrum (Gram positive and Gram negative bacteria) activities that were either more effective than or as potent as the references. The binding of two most biologically effective compounds of zinc and mercury to calf thymus DNA has also been investigated by absorption spectra.

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.

Temperature variation of the effective magnetic moment for a pentacoordinate [Co(bzimpy)Cl2] complex shows a pronounced deviation from linearity below 120 K. Quantitative analysis based on the diagonalisation of the spin Hamiltonian matrices gave the set of magnetic parameters: gx=2.501, gy=2.622, gz=1.476, D/hc=71.7 cm-1, E/hc=1.4 cm-1, alphaTIP=0.98×10-9 m3 mol-1 and zJ/hc=-0.184 cm-1 (SQUID data). The extreme value of the axial zero-field splitting parameter D shows that the magnetic anisotropy determined by the non-spherical distribution of the spin density is enhanced by the low symmetry of the pentacoordinate chromophore. For the [Mn(bzimpy)Cl2]·1/2 MeOH analogue, only a moderate ZFS is found (D/hc=-2.7 cm-1).

14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II), belongs to catalyst-palladium compound, is a common compound. Computed Properties of C10H8Cl2N2PdIn an article, once mentioned the new application about 14871-92-2.

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.

The heterocyclic ligands 2,6-bis(pyrazol-1-yl)pyridine (L1) and 2,6-bis(benzimidazol-2-yl)pyridine (L2) and their cobalt(II) complexes were synthesized. The blue five-coordinate complex [Co(L1)Cl2] isolated initially from the reaction mixture rapidly absorbed water vapour from the atmosphere to yield the pink six-coordinate complex [Co(L1)(H2O)3]Cl2. This change is reversible upon desiccation or transferring [Co(L1)(H2O)3]Cl2 into acetonitrile. The five coordinate complex [Co(L2)Cl2], however, remains stable under similar conditions. The structures of the complexes [Co(L1)Cl2], [Co(L1)(H2O)3]Cl2 and [Co(L2)Cl2] have been determined by x-ray crystallography. The magnetic susceptibilities and the electronic spectra for [Co(L1)Cl2], [Co(L2)Cl2] and [Co(L1)(H2O)3]Cl2 are presented.

14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II), belongs to catalyst-palladium compound, is a common compound. Recommanded Product: (2,2′-Bipyridine)dichloropalladium(II)In an article, once mentioned the new application about 14871-92-2.

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.
