Abstract:
The reaction of copper(I) iodide with 1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one (L, C13H19NOS) in aceto-nitrile/di-chloro-methane results in a crystalline coordination polymer, namely poly[bis-{μ2-1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one}tetra-μ3-iodido-tetra-copper(I)], [Cu4I4L2] . The asymmetric unit comprises two ligand mol-ecules, four copper(I) ions and four iodide ions. Inter-estingly, the O atoms are bound to the soft copper(I) ions. The stair-step clusters of Cu and I atoms in the asymmetric unit are linked repeatedly, giving rise to infinite chains along [100]. Neighbouring infinite chains are linked through the L mol-ecules, forming a two-dimensional brick-wall structure. These two-dimensional networks are stacked alternately along [001]. Additionally, there are inter-molecular C-H⋯I hydrogen bonds and C-H⋯π inter-actions between the ligands.

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...
