(Zr)3Co5Zr(ZrAlCo)3(Co)5(CoAl)3 crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Co clusters, three Co5Zr clusters, three CoAl clusters, three Zr clusters, and three ZrAlCo clusters. In each Co cluster, there are three inequivalent Co sites. In the first Co site, Co(6) is bonded in a single-bond geometry to one Co(4) atom. The Co(6)-Co(4) bond length is 3.37 Å. In the second Co site, Co(3) is bonded in a 2-coordinate geometry to one Co(4) and two equivalent Co(3) atoms. The Co(3)-Co(4) bond length is 2.28 Å. Both Co(3)-Co(3) bond lengths are 1.32 Å. In the third Co site, Co(4) is bonded in a distorted rectangular see-saw-like geometry to one Co(6) and three equivalent Co(3) atoms. In each Co5Zr cluster, Zr(1) is bonded in a single-bond geometry to one Co(8) atom. The Zr(1)-Co(8) bond length is 1.49 Å. There are three inequivalent Co sites. In the first Co site, Co(2) is bonded in a distorted rectangular see-saw-like geometry to one Co(8) and three equivalent Co(1) atoms. The Co(2)-Co(8) bond length is 3.37 Å. All Co(2)-Co(1) bond lengths are 2.28 Å. In the second Co site, Co(8) is bonded in a single-bond geometry to one Zr(1) and one Co(2) atom. In the third Co site, Co(1) is bonded in a 2-coordinate geometry to one Co(2) and two equivalent Co(1) atoms. Both Co(1)-Co(1) bond lengths are 1.32 Å. In each CoAl cluster, Co(5) is bonded in a single-bond geometry to one Al(2) atom. The Co(5)-Al(2) bond length is 0.89 Å. Al(2) is bonded in a 3-coordinate geometry to one Co(5) and two equivalent Al(2) atoms. Both Al(2)-Al(2) bond lengths are 0.92 Å. In each Zr cluster, Zr(3) is bonded in a 2-coordinate geometry to two equivalent Zr(3) atoms. Both Zr(3)-Zr(3) bond lengths are 0.56 Å. In each ZrAlCo cluster, Zr(2) is bonded in a 4-coordinate geometry to two equivalent Zr(2) and two equivalent Al(1) atoms. Both Zr(2)-Zr(2) bond lengths are 0.56 Å. Both Zr(2)-Al(1) bond lengths are 0.49 Å. Co(7) is bonded in a single-bond geometry to one Al(1) atom. The Co(7)-Al(1) bond length is 0.89 Å. Al(1) is bonded in a 3-coordinate geometry to two equivalent Zr(2) and one Co(7) atom.
