文摘

Two germanato-polyoxovanadates with the {Vb>15b>Geb>6b>Ob>48b>} 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 Geb>2b>Ob>7b> 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)}b>4b>Vb>15b>Geb>6b>Ob>48b>(Hb>2b>O)]^4– anion.
