Ti3(Co10B3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a cuboctahedral geometry to twelve equivalent Co(2) atoms. In the second Ti site, Ti(2) is bonded in a distorted tetrahedral geometry to four equivalent Co(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one Ti(2) and three equivalent B(1) atoms to form a mixture of corner and edge-sharing CoTiB3 tetrahedra. In the second Co site, Co(2) is bonded in a 2-coordinate geometry to one Ti(1) and two equivalent B(1) atoms. B(1) is bonded in a 8-coordinate geometry to four equivalent Co(1) and four equivalent Co(2) atoms.
