Abstract:
Synthetic di- or multimetallic complexes bearing NH nitrogenous ligands in a sulfur-rich coordination environment have attracted considerable attention due to their importance in evaluating the complex mechanism of biological nitrogen fixation. Herein, we report a series of thiolate-bridged dicobalt NH species obtained by treatment of CoIIICoIII precursor with hydrazine and its substituted derivatives at ambient temperature. Remarkably, when the substituent is the cyclohexyl group, the resulting species can interconvert through different pathways. This Co2S2 skeleton provides a new model system for obtaining valuable information about the early N2H-bound intermediate species during the catalytic cycle of nitrogenase.

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...

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...
