A glycine ligand coordinated hybrid complex constructed from hexanuclear copper clusters and octamolybdates

Self-assembly of the sodium molybdate, copper chloride and glycine in aqueous solution results in a novel compound, {[NaCu6(Gly)8(H2O)2][Mo8O26(GlyH)2(Cu(Gly)H2O)]2}{NaCu6(Gly)8(H2O)2}{Mo8O26(GlyH)2}·16H2O (1). Compound 1 contains a new unit of {[NaCu6(Gly)8(H2O)2][Mo8O26Cu(Gly)2]2}, in which the [Mo8O26Cu(Gly)2] polyoxometalate units are connected by the [NaCu6(Gly)8(H2O)2] hexanuclear copper cluster. The magnetic measurement of 1 shows that ferromagnetic coupling exists between the magnetic centers of the hexanuclear copper cluster.
