Materials Data on NiH20C12S2(NO4)2 by Materials Project
NiC4H4(SO2)2(C3NH6)2(CO)2(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four formaldehyde molecules, four trimethylamine molecules, four water molecules, and two NiC4H4(SO2)2 clusters. In each NiC4H4(SO2)2 cluster, Ni2+ is bonded in an octahedral geometry to two equivalent S2- and four O2- atoms. Both Ni–S bond lengths are 2.49 Å. There are two shorter (2.13 Å) and two longer (2.15 Å) Ni–O bond lengths. There are two inequivalent C+0.33+ sites. In the first C+0.33+ site, C+0.33+ is bonded in a single-bond geometry to one S2- atom. The C–S bond length is 1.67 Å. In the second C+0.33+ site, C+0.33+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.27 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. S2- is bonded in an L-shaped geometry to one Ni2+ and one C+0.33+ atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and one C+0.33+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Ni2+ and two H1+ atoms.
