Hf Mn Sn Ir
HfMnIrSn crystallizes in the trigonal R3m space group. Hf(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1), three equivalent Ir(1), and three equivalent Sn(1) atoms. There are three shorter (2.72 Å) and one longer (3.49 Å) Hf(1)-Mn(1) bond length. All Hf(1)-Ir(1) bond lengths are 2.70 Å. All Hf(1)-Sn(1) bond lengths are 2.70 Å. Mn(1) is bonded in a single-bond geometry to four equivalent Hf(1) and one Sn(1) atom. The Mn(1)-Sn(1) bond length is 0.49 Å. Ir(1) is bonded in a 3-coordinate geometry to three equivalent Hf(1) atoms. Sn(1) is bonded in a single-bond geometry to three equivalent Hf(1) and one Mn(1) atom.
