TaMo2Zn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaMo2Zn clusters. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Mo(1) atoms. Both Ta(1)-Mo(1) bond lengths are 0.61 Å. Mo(1) is bonded in a 3-coordinate geometry to one Ta(1), one Mo(1), and one Zn(1) atom. The Mo(1)-Mo(1) bond length is 0.44 Å. The Mo(1)-Zn(1) bond length is 1.17 Å. Zn(1) is bonded in a 2-coordinate geometry to two equivalent Mo(1) atoms.
