Mg Mg In Ir
Mg2IrIn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Mg2IrIn clusters. Mg(1) is bonded in an L-shaped geometry to one Ir(1) and one In(1) atom. The Mg(1)-Ir(1) bond length is 0.52 Å. The Mg(1)-In(1) bond length is 0.52 Å. Ir(1) is bonded in an L-shaped geometry to two equivalent Mg(1) atoms. In(1) is bonded in an L-shaped geometry to two equivalent Mg(1) atoms.
