Di-?-chlorido-bis-{chlorido[(R)/(S)-1,5-di-phenyl-3-(2-pyridyl-?N)-2-pyrazoline-?N]zinc(II)}.

ABSTRACT: In the centrosymmetric binuclear title compound, [Zn(2)Cl(4)(C(20)H(17)N(3))(2)], the coordination geometry of the Zn(II) ion can be described as a distorted ZnN(2)Cl(3) trigonal bipyramid (? = 0.89), arising from the N,N'-bidentate ligand, a terminal chloride ion and two bridging chloride ions. The N atoms occupy one axial and one equatorial site and the terminal chloride ion occupies an equatorial site. The dihedral angle between the pyridine and pyrazole rings is 12.8?(2)°. In the crystal, aromatic ?-? stacking [centroid-centroid separations = 3.812?(3) and 3.848?(3)?Å] and C-H?Cl and C-H?? inter-actions help to establish the packing.
