(Ta)2ZnCo crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ta clusters and two ZnCo clusters. In each Ta cluster, there are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a distorted single-bond geometry to one Ta(2) atom. The Ta(1)-Ta(2) bond length is 1.01 Å. In the second Ta site, Ta(2) is bonded in a 1-coordinate geometry to one Ta(1) atom. In each ZnCo cluster, Co(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Co(1)-Zn(1) bond length is 1.37 Å. Zn(1) is bonded in a distorted single-bond geometry to one Co(1) atom.
