K Ga Ir Ir
KIr2Ga is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KIr2Ga clusters. K(1) is bonded in a 3-coordinate geometry to two equivalent Ir(1) and one Ga(1) atom. Both K(1)-Ir(1) bond lengths are 0.44 Å. The K(1)-Ga(1) bond length is 0.32 Å. Ir(1) is bonded in a 3-coordinate geometry to one K(1), one Ir(1), and one Ga(1) atom. The Ir(1)-Ir(1) bond length is 0.32 Å. The Ir(1)-Ga(1) bond length is 0.44 Å. Ga(1) is bonded in a distorted single-bond geometry to one K(1) and two equivalent Ir(1) atoms.
