Materials Data on NiH7C3NO6 by Materials Project
NiH3(CO2)3NH4 crystallizes in the monoclinic C2 space group. The structure is three-dimensional and consists of four ammonium molecules and one NiH3(CO2)3 framework. In the NiH3(CO2)3 framework, Ni2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Ni–O bond distances ranging from 2.07–2.15 Å. There are four inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. Both C–O bond lengths are 1.27 Å. In the second C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two equivalent O2- atoms. The C–H bond length is 1.10 Å. Both C–O bond lengths are 1.27 Å. In the third C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. Both C–O bond lengths are 1.27 Å. In the fourth C2+ site, C2+ is bonded in a trigonal planar geometry to one H1+ and two equivalent O2- atoms. The C–H bond length is 1.10 Å. Both C–O bond lengths are 1.27 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ni2+ and one C2+ atom.
