Materials Data on NiH6(SO6)2 by Materials Project
Ni(HO)4(HSO4)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two sulfur trioxide monohydrate molecules and one Ni(HO)4 cluster. In the Ni(HO)4 cluster, Ni is bonded in a square co-planar geometry to four O atoms. There is two shorter (1.73 Å) and two longer (2.16 Å) Ni–O bond length. There are two inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.99 Å. In the second H site, H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.99 Å. There are two inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one Ni and one H atom. In the second O site, O is bonded in a bent 150 degrees geometry to one Ni and one H atom.
