VZnSn crystallizes in the trigonal R3m space group. V(1) is bonded to one Zn(1) and three equivalent Sn(1) atoms to form distorted VZnSn3 tetrahedra that share corners with three equivalent Zn(1)VSn3 tetrahedra, corners with six equivalent V(1)ZnSn3 tetrahedra, and edges with three equivalent Zn(1)VSn3 tetrahedra. The V(1)-Zn(1) bond length is 1.98 Å. All V(1)-Sn(1) bond lengths are 2.73 Å. Zn(1) is bonded to one V(1) and three equivalent Sn(1) atoms to form distorted ZnVSn3 tetrahedra that share corners with three equivalent V(1)ZnSn3 tetrahedra, corners with six equivalent Zn(1)VSn3 tetrahedra, and edges with three equivalent V(1)ZnSn3 tetrahedra. All Zn(1)-Sn(1) bond lengths are 2.73 Å. Sn(1) is bonded in a distorted hexagonal planar geometry to three equivalent V(1) and three equivalent Zn(1) atoms.
