B Mo Mo W
WMo2B is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WMo2B clusters. W(1) is bonded in a 3-coordinate geometry to two equivalent Mo(1) and one B(1) atom. Both W(1)-Mo(1) bond lengths are 0.52 Å. The W(1)-B(1) bond length is 0.52 Å. Mo(1) is bonded in a 3-coordinate geometry to one W(1), one Mo(1), and one B(1) atom. The Mo(1)-Mo(1) bond length is 0.52 Å. The Mo(1)-B(1) bond length is 0.52 Å. B(1) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Mo(1) atoms.
