Materials Data on Mg3(PO4)2 by Materials Project
Abstract
Mg3(PO4)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two nemalite molecules and one Mg5(P2O7)2 sheet oriented in the (0, -1, 1) direction. In the Mg5(P2O7)2 sheet, there are five inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded in a 5-coordinate geometry to two O2- atoms. There is one shorter (1.96 Å) and one longer (2.03 Å) Mg–O bond length. In the second Mg2+ site, Mg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 1.82–2.45 Å. In the third Mg2+ site, Mg2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Mg–O bond distances ranging from 2.01–2.19 Å. In the fourth Mg2+ site, Mg2+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (2.15 Å) Mg–O bond length. In the fifth Mg2+ site, Mg2+ is bonded in a 1-coordinate geometry to three O2- atoms. There are a spread of Mg–O bond distances ranging from 1.82–2.30 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in amore »
