Abstract:
Two novel homoleptic ruthenium (II) complexes containing asymmetric tridentate ligands, 2-(benzimidazole-2-yl)-1,10-phenanthroline (PHBI) and 2-(naphtho[2,3-d]imidazole-2-yl)-1,10-phenanthroline (PHNI) have been synthesized and characterized by elemental analysis, mass spectra, (1)H NMR, and electronic spectroscopy. The DNA-binding properties of the complexes have been investigated by spectroscopic methods and viscosity measurements. The results indicate that the two complexes interact with DNA via electrostatic interaction, and the mechanisms of DNA binding with the complexes have also been discussed.

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 be...
