In In In In Os
OsIn4 is Iron carbide-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three OsIn4 clusters. Os(1) is bonded in a distorted single-bond geometry to one In(2) atom. The Os(1)-In(2) bond length is 2.23 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one In(2) atom. The In(1)-In(2) bond length is 1.08 Å. In the second In site, In(2) is bonded in a tetrahedral geometry to one Os(1) and three equivalent In(1) atoms.
