By adjusting the pH of the reaction medium, the stoichiometry, the reactant concentrations, and heating time and temperature, reactive mono- and binuclear Ru(III) and Rh(III) chloro aqua complexes and various hydrazone tautomers were obtained. This provided for the synthesis of new complexes promising as cardiotonic agents and analytical forms for determination of metal traces in solutions. Correlation analysis was applied to describe the type of M-L chemical bonding. The ruthenium formal oxidation state and local environment in the coordination polyhedra of the synthesized complexes were determined by X-ray photoelectron spectroscopy.
