Title: Materials Data on MgH2(CO2)2 by Materials Project

Abstract

Mg(HCOO)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to six O2- atoms to form edge-sharing MgO6 octahedra. There are a spread of Mg–O bond distances ranging from 2.04–2.15 Å. In the second Mg2+ site, Mg2+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MgO6 octahedra. The corner-sharing octahedra tilt angles range from 64–66°. There are a spread of Mg–O bond distances ranging from 2.09–2.13 Å. In the third Mg2+ site, Mg2+ is bonded to six O2- atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 64°. There are four shorter (2.08 Å) and two longer (2.16 Å) Mg–O bond lengths. In the fourth Mg2+ site, Mg2+ is bonded to six O2- atoms to form corner-sharing MgO6 octahedra. The corner-sharing octahedral tilt angles are 66°. There are a spread of Mg–O bond distances ranging from 2.05–2.16 Å. There are six 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 1.11 Å.

In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2+ atom. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Mg2+ and one C2+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one C2+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one C2+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one C2+ atom.

In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one C2+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mg2+ and one C2+ atom. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Mg2+ and one C2+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mg2+ and one C2+ atom.« less
