In2(Co7B2)3 crystallizes in the cubic Fm-3m space group. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a cuboctahedral geometry to twelve equivalent Co(3) atoms. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to one In(1) and three equivalent B(1) atoms. In the third Co site, Co(3) is bonded in a distorted bent 150 degrees geometry to one Co(1) and two equivalent B(1) atoms. In(1) is bonded in a distorted tetrahedral geometry to four equivalent Co(2) atoms. B(1) is bonded in a 8-coordinate geometry to four equivalent Co(2) and four equivalent Co(3) atoms.
In2(Co7B2)3 crystallizes in the cubic Fm-3m space group. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a cuboctahedral geometry to twelve equivalent Co(3) atoms. All Co(1)-Co(3) bond lengths are 2.50 Å. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to one In(1) and three equivalent B(1) atoms. The Co(2)-In(1) bond length is 2.50 Å. All Co(2)-B(1) bond lengths are 2.06 Å. In the third Co site, Co(3) is bonded in a distorted bent 150 degrees geometry to one Co(1) and two equivalent B(1) atoms. Both Co(3)-B(1) bond lengths are 2.11 Å. In(1) is bonded in a distorted tetrahedral geometry to four equivalent Co(2) atoms. B(1) is bonded in a 8-coordinate geometry to four equivalent Co(2) and four equivalent Co(3) atoms.
