Mg Mg In Ir
(Mg)2IrIn is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrIn clusters and two Mg clusters. In each IrIn cluster, Ir(1) is bonded in a single-bond geometry to one In(1) atom. The Ir(1)-In(1) bond length is 1.76 Å. In(1) is bonded in a 1-coordinate geometry to one Ir(1) atom. In each Mg cluster, there are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted single-bond geometry to one Mg(2) atom. The Mg(1)-Mg(2) bond length is 0.39 Å. In the second Mg site, Mg(2) is bonded in a single-bond geometry to one Mg(1) atom.
