Ir2GeAs crystallizes in the triclinic P1 space group. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), two equivalent Ge(1), and two equivalent As(1) atoms. Both Ir(1)-Ir(1) bond lengths are 2.97 Å. There is one shorter (2.14 Å) and one longer (2.42 Å) Ir(1)-Ir(2) bond length. There is one shorter (3.03 Å) and one longer (3.08 Å) Ir(1)-Ge(1) bond length. There is one shorter (2.74 Å) and one longer (2.80 Å) Ir(1)-As(1) bond length. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), two equivalent Ge(1), and two equivalent As(1) atoms. Both Ir(2)-Ir(2) bond lengths are 2.97 Å. There is one shorter (2.74 Å) and one longer (2.80 Å) Ir(2)-Ge(1) bond length. There is one shorter (3.03 Å) and one longer (3.08 Å) Ir(2)-As(1) bond length. Ge(1) is bonded in a single-bond geometry to two equivalent Ir(1), two equivalent Ir(2), and one As(1) atom. The Ge(1)-As(1) bond length is 0.16 Å. As(1) is bonded in a single-bond geometry to two equivalent Ir(1), two equivalent Ir(2), and one Ge(1) atom.
