Mo W
WMo crystallizes in the monoclinic Cm space group. W(1) is bonded in a 10-coordinate geometry to six equivalent W(1) and four equivalent Mo(1) atoms. All W(1)-W(1) bond lengths are 2.77 Å. There are a spread of W(1)-Mo(1) bond distances ranging from 2.53-3.13 Å. Mo(1) is bonded in a 10-coordinate geometry to four equivalent W(1) and six equivalent Mo(1) atoms. All Mo(1)-Mo(1) bond lengths are 2.77 Å.
