Abstract
In this research study, the formation of rhenium(I) complexes with bidentate carbohydrazide Schiff bases are reported. More specifically, the respective coordination reactions of [Re(CO)5Cl] with N-[1,3-benzothiazol-2-ylmethylidene]pyridine-2-carbohydrazide (bzpc), N-[1,3-benzothiazol-2-ylmethylidene]thiophene-2-carbohydrazide (bztc) and N-[(4-oxo-4H-chromen-3-yl)methylidene]thiophene-2-carbohydrazide (chrtc) afforded the rhenium(I) complexes, fac-[Re(CO)3Cl(L)] {L = bzpc for 1, bztc for 2 and chrtc for 3). Single crystal X-ray studies supported by spectroscopic characterization confirmed that the ligands coordinated mutually as bidentate neutral chelating moieties to their fac-[Re(CO)3Cl] cores. The DNA interactions of the metal complexes were evaluated using UV–Vis DNA binding titrations and gel electrophoresis. The redox properties of the metal complexes were probed using voltammetry and DFT studies were used to rationalize the variable coordination modes of 1 and 2 compared to 3.
