Redetermination of (2,2'-bipyridine-?N,N')dichlorido-palladium(II) dichloro-methane solvate.

ABSTRACT: In the title compound, [PdCl(2)(C(10)H(8)N(2))]·CH(2)Cl(2), the Pd(2+) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the 2,2'-bipyridine (bipy) ligand and two chloride ions. The compound displays intra-molecular C-H?Cl hydrogen bonds and pairs of complex mol-ecules are connected by inter-molecular C-H?Cl hydrogen bonds. Inter-molecular ?-? inter-actions are present between the pyridine rings of the ligand, the shortest centroid-centroid distance being 4.096?(3)?Å. As a result of the electronic nature of the chelate ring, it is possible to create ?-? inter-actions to its symmetry-related counterpart [3.720?(2)?Å] and also with a pyridine ring [3.570?(3)?Å] of the bipy unit. The present structure is a redetermination of a previous structure [Vicente et al. (1997 ?). Private communication (refcode PYCXMN02). CCDC, Cambridge, England]. In the new structure refinement all H atoms were located in a difference Fourier synthesis. Their coordinates were refined freely, together with isotropic displacement parameters.
