Ga Ga Ir Pt
IrPtGa2 crystallizes in the monoclinic Cm space group. Ir(1) is bonded to four equivalent Ir(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted face and corner-sharing IrGa8Ir4 cuboctahedra. All Ir(1)-Ir(1) bond lengths are 2.91 Å. There are a spread of Ir(1)-Ga(1) bond distances ranging from 2.95-3.18 Å. There are a spread of Ir(1)-Ga(2) bond distances ranging from 2.97-3.21 Å. Pt(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ga(1) and four equivalent Ga(2) atoms. There are a spread of Pt(1)-Ga(1) bond distances ranging from 2.24-2.55 Å. There are a spread of Pt(1)-Ga(2) bond distances ranging from 2.24-2.55 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to four equivalent Ir(1) and four equivalent Pt(1) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to four equivalent Ir(1) and four equivalent Pt(1) atoms.
