In Ge W W W W
W4InGe crystallizes in the trigonal R3m space group. There are two inequivalent W sites. In the first W site, W(2) is bonded in a 6-coordinate geometry to three equivalent W(1) and three equivalent Ge(1) atoms. All W(2)-W(1) bond lengths are 1.04 Å. All W(2)-Ge(1) bond lengths are 3.25 Å. In the second W site, W(1) is bonded in a 4-coordinate geometry to one W(2), two equivalent W(1), and one In(1) atom. Both W(1)-W(1) bond lengths are 0.60 Å. The W(1)-In(1) bond length is 1.15 Å. In(1) is bonded in a 4-coordinate geometry to three equivalent W(1) and one Ge(1) atom. The In(1)-Ge(1) bond length is 1.34 Å. Ge(1) is bonded in a single-bond geometry to three equivalent W(2) and one In(1) atom.
