Abstract: | New water soluble Ru(II) binary complex [Ru(C5H7N3)(X)(H2O)2] with 2-hydrazinopyridine and its ternary complexes with X = dichloride, oxalate, malonate or pyrophosphate ligands have been synthesized. The complexes have been characterized using elemental analyses, mass, IR, and UV-Vis. spectroscopies, cyclic voltammetry, magnetic susceptibility, and thermal analysis. The complexes are diamagnetic and the electronic spectral data showed that peaks are due to low spin octahedral Ru(II) complexes. The optimized structures of the complexes 1‒4 indicate distorted octahedral geometry with bond angles around the ruthe nium atom ranged from 80.44° to 99.64°. The values of the electronic energies (‒635 to ‒1145 a.u.), the high est occupied molecular orbital energies (‒0.181 to 0.073 a.u.) and lowest unoccupied molecular orbital ener gies (‒0.056 to 0.167 a.u.) indicate the stability of the complexes. The complexes are polarized as indicated from the dipole moment values (9.39‒14.27 Debye). The complexes have noticeable cytotoxicity with IC50 (μM): 0.011‒0.062 (HepG-2), 0.015‒0.080 (MCF-7), 0.015‒0.116 (HCT-116), and PC-3 (0.034‒0.125). |
