Zn Ge W
WZnGe crystallizes in the trigonal R3m space group. W(1) is bonded in a single-bond geometry to one Zn(1) and three equivalent Ge(1) atoms. The W(1)-Zn(1) bond length is 0.22 Å. All W(1)-Ge(1) bond lengths are 3.04 Å. Zn(1) is bonded in a single-bond geometry to one W(1) and three equivalent Ge(1) atoms. All Zn(1)-Ge(1) bond lengths are 2.80 Å. Ge(1) is bonded to three equivalent W(1) and three equivalent Zn(1) atoms to form edge-sharing GeZn3W3 octahedra.
