Abstract:
A dinitrogen-bridged diruthenium complex bearing 2,6-pyridine-dicarboxylate (pydc2-), which coordinates in a κ2-ON bidentate mode, with ammine and hydroxido ligands has been synthesized by reactions of ruthenium(III) and/or ruthenium(II) complexes with hydrazine or dinitrogen as a dinitrogen source. A reaction of the diruthenium complex with pyridine affords a pyridine-substituted diruthenium complex. The electronic structures of the diruthenium complexes in a mixed-valence state have been investigated using UV-vis-NIR and IR spectroscopy and electrochemical methods.

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...
