Ti(IV)-centered dynamic interconversion between Pd(II), Ti(IV)-containing ring and cage molecules
Heteronuclear, supramolecular ring and cage complexes have been constructed from a pyridyl catechol ligand, TiO(aca)(2), and PdCl2(CH3CN2). These two complexes are quantitatively interconvertible, in which Ti4+ centered coordination changes take place between a well-known Ti(catecholato)(3) and a newly established TiH(catecholato)(2)(acetylacetonato) structures. The Ti4+-centered structural changes arise from the changes in the component fraction basicity condition.
