Cs Ac Ho Ho
CsAcHo2 crystallizes in the trigonal R3m space group. Cs(1) is bonded in a distorted single-bond geometry to three equivalent Ac(1) and one Ho(1) atom. All Cs(1)-Ac(1) bond lengths are 3.56 Å. The Cs(1)-Ho(1) bond length is 2.65 Å. Ac(1) is bonded to three equivalent Cs(1), one Ho(1), and one Ho(2) atom to form distorted corner-sharing AcCs3Ho2 trigonal bipyramids. The Ac(1)-Ho(1) bond length is 2.65 Å. The Ac(1)-Ho(2) bond length is 2.65 Å. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a linear geometry to one Cs(1) and one Ac(1) atom. In the second Ho site, Ho(2) is bonded in a distorted single-bond geometry to one Ac(1) atom.
