Materials Data on VCu3Te4 by Materials Project
Cu3VTe4 is Sulvanite structured and crystallizes in the cubic P-43m space group. The structure is three-dimensional. V5+ is bonded to four equivalent Te2- atoms to form VTe4 tetrahedra that share edges with six equivalent CuTe4 tetrahedra. All V–Te bond lengths are 2.58 Å. Cu1+ is bonded to four equivalent Te2- atoms to form CuTe4 tetrahedra that share corners with eight equivalent CuTe4 tetrahedra and edges with two equivalent VTe4 tetrahedra. All Cu–Te bond lengths are 2.57 Å. Te2- is bonded to one V5+ and three equivalent Cu1+ atoms to form a mixture of distorted edge and corner-sharing TeVCu3 tetrahedra.
