Materials Data on ZnH9C4NO6 by Materials Project

ZnH3(CO2)3CH3NH3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four methylammonium molecules and one ZnH3(CO2)3 framework. In the ZnH3(CO2)3 framework, Zn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.11–2.21 Å. There are two inequivalent C1+ sites. In the first C1+ site, C1+ 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 second C1+ site, C1+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. There is one shorter (1.27 Å) and one longer (1.28 Å) C–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one C1+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Zn2+ and one C1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one C1+ atom.
