Y Ta Mo Mo
YTaMo2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YTaMo2 clusters. Y(1) is bonded in a 2-coordinate geometry to two equivalent Mo(1) atoms. Both Y(1)-Mo(1) bond lengths are 2.26 Å. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Mo(1) atoms. Both Ta(1)-Mo(1) bond lengths are 2.26 Å. Mo(1) is bonded in a 2-coordinate geometry to one Y(1) and one Ta(1) atom.
