Y Co Mo Mo
YMo2Co crystallizes in the monoclinic Cm space group. Y(1) is bonded in a 9-coordinate geometry to four equivalent Y(1), one Mo(1), and four equivalent Co(1) atoms. All Y(1)-Y(1) bond lengths are 2.88 Å. The Y(1)-Mo(1) bond length is 3.02 Å. There are a spread of Y(1)-Co(1) bond distances ranging from 2.53-2.90 Å. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 5-coordinate geometry to one Y(1) and four equivalent Mo(2) atoms. There are a spread of Mo(1)-Mo(2) bond distances ranging from 2.06-2.50 Å. In the second Mo site, Mo(2) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Co(1) atom. The Mo(2)-Co(1) bond length is 2.45 Å. Co(1) is bonded in a 9-coordinate geometry to four equivalent Y(1), one Mo(2), and four equivalent Co(1) atoms. All Co(1)-Co(1) bond lengths are 2.88 Å.
