Ca Ga Ir Ir
CaIr2Ga crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaIr2Ga clusters. Ca(1) is bonded in a single-bond geometry to one Ir(2) atom. The Ca(1)-Ir(2) bond length is 1.89 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Ir(2) and one Ga(1) atom. The Ir(1)-Ir(2) bond length is 0.27 Å. The Ir(1)-Ga(1) bond length is 2.56 Å. In the second Ir site, Ir(2) is bonded in a linear geometry to one Ca(1) and one Ir(1) atom. Ga(1) is bonded in a single-bond geometry to one Ir(1) atom.
