Synthesis, spectroscopic and structural characterizations of two new complexes of ruthenium with 2-(hydroxymethyl)benzimidazole and 1,10-phenanthroline ligands

The complexes [RuCl(CO)(PPh3)2(HBIm)] and [RuH(CO)(PPh3)2(1,10-phen)]Cl·H2O·(CH3)2O have been prepared and studied by IR and UV–Vis spectroscopy, and X-ray crystallography. The complexes were prepared in the reactions of [RuHCl(CO)(PPh3)3] with 2-(hydroxymethyl)benzimidazole or 1,10-phenanthroline two hydrate in acetone. The electronic spectra of the obtained compounds have been calculated using the TDDFT method. The luminescence properties of these complexes were examined.
