description: Ti7B8(IrRh2)2 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are seven inequivalent Ti sites. In the first Ti site, Ti is bonded to twelve B atoms to form face-sharing TiB12 cuboctahedra. All Ti–B bond lengths are 2.40 Å. In the second Ti site, Ti is bonded in a 11-coordinate geometry to four Ir, two equivalent Rh, and five B atoms. There are two shorter (2.69 Å) and two longer (2.89 Å) Ti–Ir bond lengths. Both Ti–Rh bond lengths are 2.72 Å. There are a spread of Ti–B bond distances ranging from 2.34–2.61 Å. In the third Ti site, Ti is bonded in a 11-coordinate geometry to two equivalent Ir, four Rh, and five B atoms. Both Ti–Ir bond lengths are 2.68 Å. There are two shorter (2.72 Å) and two longer (2.89 Å) Ti–Rh bond lengths. There are a spread of Ti–B bond distances ranging from 2.34–2.61 Å.
