Abstract:
The crystal structure of the title compound, [Ni(C14H8F2S2)2] (I), reveals averaged S-C [1.708 (2) Å] and C-Cchelate [1.395 (4) Å] bond lengths that are consistent with radical monoanionic ligands paired with a divalent Ni2+ ion. Mol-ecules of I associate as dyads via inter-molecular Ni⋯S close contacts of 3.396 (2) Å. This close association is enabled by a bending of both di-thiol-ene ligands to the same side and away from the NiS4 planar inter-ior such that the angle between the seven atom mean planes defined by each NiS2C2 ring and the first C atom of each aryl substituent is 22.91 (8)°. These dyads form sheets in the bc plane that are held together in part by inter-molecular C-H⋯F hydrogen bonds of 2.47 (4) Å.

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...
