Abstract

The compound {[Cu(C5H14N2)2]3[V15As6O42(H2O)]} was synthesized under solvothermal conditions. During the reaction the VV species of NH4VO3 are reduced to VIV providing the 15 reduced VIV centers in the anionic cluster. The compound crystallizes in the non-centrosymmetric orthorhombic space group P212121 with four formula units in the cell, V = 9464.8(4) Å3. The structure features [V15As6O42(H2O)]6− anions which are joinded by Cu2+-centered complexes to form linear chains. If a long Cu–O bond is considered as weak intermolecular interaction a three-dimensional network is generated. The compound is partially soluble in water as evidenced by UV/Vis spectroscopy and mass spectra. The magnetic susceptibility of the compound is dominated by strong intra-cluster antiferromagnetic exchange interactions.
