Materials Data on MgP(CO3)2 by Materials Project

MgP(CO3)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Mg2+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.00–2.68 Å. There are two inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.19 Å. In the second C+2.50+ site, C+2.50+ is bonded in a bent 150 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.23 Å. P5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.50–1.55 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Mg2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Mg2+ and one C+2.50+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Mg2+ and one C+2.50+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one C+2.50+ atom.

Materials Data on MgP(CO4)2 by Materials Project

MgP(CO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two MgP(CO4)2 ribbons oriented in the (0, 0, 1) direction. Mg is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Mg–O bond distances ranging from 1.95–2.62 Å. There are two inequivalent C sites. In the first C site, C is bonded in a distorted linear geometry to one P and one O atom. The C–P bond length is 2.00 Å. The C–O bond length is 1.14 Å. In the second C site, C is bonded in a linear geometry to two O atoms. There is one shorter (1.17 Å) and one longer (1.18 Å) C–O bond length. P is bonded in a distorted trigonal planar geometry to one C and three O atoms. There are a spread of P–O bond distances ranging from 1.47–1.52 Å. There are eight inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Mg and one C atom. In the second O site, O is bonded in a single-bond geometry to one C atom. In the third O site, O is bonded in a single-bond geometry to one Mg atom. In the fourth O site, O is bonded in a single-bond geometry to one Mg atom. In the fifth O site, O is bonded in a single-bond geometry to one P atom. In the sixth O site, O is bonded in a bent 150 degrees geometry to one Mg and one P atom. In the seventh O site, O is bonded in a bent 150 degrees geometry to one Mg and one P atom. In the eighth O site, O is bonded in a single-bond geometry to one C atom.
