Three oxidation states (+2, +3, +4) of an octahedral nickel center were stabilized in a newly prepared RhNiRh trinuclear complex, [Ni{Rh(apt) } ] (apt=3- aminopropanethiolate), in which the nickel center was bound by six thiolato donors sourced from two redox-inert fac-[Rh (apt) ] octahedral units. The three oxidation states of the octahedral nickel center were fully characterized by single-crystal X-ray crystallography, as well as spectroscopic, electrochemical, and magnetic measurements; all three were interconvertible, and the conversion was accompanied by changes in color, magnetism, and Jahn-Teller distortion.

Heterometallic coordination polymers are emerging as a class of crystalline materials for sustainable energy production via electrocatalysis thanks to the synergistic and cooperative effects of different kinds of metal centres...

Tris(2-pyridylthio)methane (tptmH) reacts with ZnCl(2) producing the Zn-C containing complex of [ZnCl(tptm)], whose cyclic voltammogram shows an irreversible oxidation peak at 0.2 V vs. E(0')(Fc(+/0)). DFT calculations suggested that 1e(-) oxidation should occur at the tptm ligand resulting in the cleavage of the Zn-C bond, leading to decomposition of the complex.
