Abstract

Abstract : Two new neutral mixed-ligand cobalt(II) complexes, [CoCl2 (dmdphphen)]1 and [Co(NCS)2 (dmdphphen)] 2, where dmdphphen is 2, 9-dimethyl-4, 7-diphenyl-1, 10-phenanthroline, were synthesized and characterized by an elemental analysis, UV-Vis, IR, TG/DTA, cyclic voltammetry CV, and single X-ray diffraction. Complex2 crystallized as monoclinic with a space group P21 /c. Co(II) ions are located in a distorted tetrahedral environment. TG/DTA result shows that these complexes are very stable and decomposed through one-step reaction. The two complexes exhibit a quasireversible one-electron response at −550 and 580 mV versus Cp2 Fe/Cp2 Fe +, which has been assigned to Co(I)/Co(II) and Co(II)/Co(III) couples. Absorption spectral studies reveal that such complexes exhibit hypochromicity during their interaction with CT-DNA.
