Hf Mn Ir Ir
HfMnIr2 crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 7-coordinate geometry to one Mn(1), three equivalent Ir(1), and three equivalent Ir(2) atoms. The Hf(1)-Mn(1) bond length is 1.87 Å. All Hf(1)-Ir(1) bond lengths are 2.74 Å. All Hf(1)-Ir(2) bond lengths are 2.74 Å. Mn(1) is bonded in a 1-coordinate geometry to one Hf(1), three equivalent Ir(2), and four equivalent Ir(1) atoms. All Mn(1)-Ir(2) bond lengths are 2.74 Å. There is one shorter (2.69 Å) and three longer (2.76 Å) Mn(1)-Ir(1) bond lengths. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to three equivalent Hf(1), four equivalent Mn(1), and one Ir(2) atom. The Ir(1)-Ir(2) bond length is 1.87 Å. In the second Ir site, Ir(2) is bonded in a 7-coordinate geometry to three equivalent Hf(1), three equivalent Mn(1), and one Ir(1) atom.
