文摘
Two germanato-polyoxovanadates with the {V15Ge6O48} cluster core are extended by covalent bonds to four transition metal amine complexes [M(tren)]2+ (M = Co and Zn, tren = tris(2-aminoethyl)amine). The complexes have bonds to terminal atoms of the Ge2O7 units and such expansion of a germanato-polyxovanadate was never observed before. The characterization of these compounds revealed the presence of two protonated tren molecules charge balancing the negative charges of the [{M(tren)}4V15Ge6O48(H2O)]4– anion.
