Al Cd Ga Ir
IrCdGaAl crystallizes in the trigonal R3m space group. Ir(1) is bonded in a distorted single-bond geometry to three equivalent Cd(1), four equivalent Ga(1), and one Al(1) atom. All Ir(1)-Cd(1) bond lengths are 2.70 Å. There is one shorter (2.59 Å) and three longer (2.87 Å) Ir(1)-Ga(1) bond lengths. The Ir(1)-Al(1) bond length is 1.71 Å. Cd(1) is bonded in a 10-coordinate geometry to three equivalent Ir(1), three equivalent Ga(1), and four equivalent Al(1) atoms. All Cd(1)-Ga(1) bond lengths are 2.70 Å. There is one shorter (2.59 Å) and three longer (2.87 Å) Cd(1)-Al(1) bond lengths. Ga(1) is bonded in a 10-coordinate geometry to four equivalent Ir(1), three equivalent Cd(1), and three equivalent Al(1) atoms. All Ga(1)-Al(1) bond lengths are 2.70 Å. Al(1) is bonded in a single-bond geometry to one Ir(1), four equivalent Cd(1), and three equivalent Ga(1) atoms.
