Abstract:
The title compound, (C12H11N3)2[Cd2Cl8], consists of two discrete 2-(3-pyridinio)benzimidazolium cations and one [Cd2Cl8]4- anion. The dimeric [Cd2Cl8]4- anion lies about an inversion centre and consists of two distorted [CdCl5] trigonal bipyramids which share a common edge. The two Cd atoms are each coordinated by two mu-Cl atoms and three terminal Cl atoms, with a Cd...Cd separation of 3.9853 (6) A. The packing displays two-dimensional hydrogen-bonded sheets, which are further linked by C-H...Cl contacts and pi-pi stacking interactions to yield a three-dimensional network.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

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...
