Ac Ac Ho Ir
Ac2HoIr is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Ac2HoIr clusters. There are two inequivalent Ac sites. In the first Ac site, Ac(1) is bonded in a linear geometry to one Ho(1) and one Ir(1) atom. The Ac(1)-Ho(1) bond length is 0.86 Å. The Ac(1)-Ir(1) bond length is 0.86 Å. In the second Ac site, Ac(2) is bonded in a single-bond geometry to one Ir(1) atom. The Ac(2)-Ir(1) bond length is 0.86 Å. Ho(1) is bonded in a single-bond geometry to one Ac(1) atom. Ir(1) is bonded in a linear geometry to one Ac(1) and one Ac(2) atom.
