Abstract:
The title compound, bis(micro-1,2-benzenethiolato)-1:2kappa(3)S,S':S';2:1kappa(3)S,S':S'-bis[(2,2'-bipyridine-kappa(2)N,N')zinc(II)], [Zn(2)(micro-C(6)H(4)S(2))(2)(C(10)H(8)N(2))(2)], crystallizes with the dinuclear molecule located on a center of symmetry. The coordination geometry about the Zn atom is a modestly distorted trigonal bipyramid, with the axial ligating atoms at an angle of 170.81 (4) degrees and the angles in the equatorial plane in the range 112.94 (4)-129.95 (4) degrees. Weak pi-stacking interactions between bipyridine ligands on adjacent molecules [interplanar spacing = 3.315 (3) A] and a possible weak intermolecular C-H.S hydrogen bond (H.S = 2.84 A) are seen in the crystal.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
