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.
