Abstract:
The title compound, [Ni(S2C2(C6H4-p-Cl)2)2] or [Ni(C14H8Cl2S2)2], crystallizes in the triclinic space group P as pairs of mol-ecules disposed about an inversion center at the bc face of the cell. Close inter-molecular C-H⋯S (2.884 Å) and C-H⋯Ni (3.032 Å) contacts that are less than the sum of the van der Waals radii appear to induce slight bowing of the mol-ecular planes toward one another. The angles at which the four p-ClC6H4- rings join the NiS2C2 chelate rings [39.37 (9)- 53.41 (6)°] are similarly influenced by these inter-molecular contacts. In the larger packing arrangement, sheets of mol-ecules extend in the direction of the ac face diagonal.

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...

02:34Structural 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...

02:46Crystal 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,...
