The First Heterotrinuclear Confacial Trioctahedron NiIITiIVCrIII: Rational Modular Assembly and Cooperative Effects

The heterodinuclear complex [(ioan)(NiTiIV)-Ti-II] with a facial O-3 donor set of Ti-IV-coordinated benzyl alcoholates serves as a metallo-ligand for a {(CrCl3)-Cl-III} fragment to yield the heterotrinuclear complex [(ioan)(NiTiCrCl3)-Ti-II-Cr-IV-Cl-III]. Comparisons of their molecular structures and electrochemical properties exhibit strong cooperative effects between the metal ions.
