As As Ir Au
IrAuAs2 crystallizes in the triclinic P1 space group. Ir(1) is bonded in a single-bond geometry to one Au(1) and two equivalent As(1) atoms. The Ir(1)-Au(1) bond length is 0.39 Å. There is one shorter (2.65 Å) and one longer (2.88 Å) Ir(1)-As(1) bond length. Au(1) is bonded in a single-bond geometry to one Ir(1), two equivalent As(1), and two equivalent As(2) atoms. There is one shorter (2.88 Å) and one longer (3.09 Å) Au(1)-As(1) bond length. There is one shorter (2.65 Å) and one longer (2.88 Å) Au(1)-As(2) bond length. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to two equivalent Ir(1), two equivalent Au(1), and two equivalent As(2) atoms. There is one shorter (2.19 Å) and one longer (2.50 Å) As(1)-As(2) bond length. In the second As site, As(2) is bonded in a 4-coordinate geometry to two equivalent Au(1) and two equivalent As(1) atoms.
