Materials Data on Mg(NO6)2 by Materials Project

MgO6(NO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four nitric acid molecules and two MgO6 clusters. In each MgO6 cluster, Mg is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Mg–O bond distances ranging from 1.93–2.60 Å. There are three inequivalent O sites. In the first O site, O is bonded in an L-shaped geometry to one Mg and one O atom. The O–O bond length is 1.25 Å. In the second O site, O is bonded in a single-bond geometry to one Mg atom. In the third O site, O is bonded in a 1-coordinate geometry to one Mg and one O atom.

Materials Data on Mg2S3(NO6)2 by Materials Project

Mg2(SO4)3N2 crystallizes in the cubic P2_13 space group. The structure is three-dimensional and consists of eight ammonia molecules and one Mg2(SO4)3 framework. In the Mg2(SO4)3 framework, there are two inequivalent Mg2+ sites. In the first Mg2+ site, Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.09 Å) Mg–O bond lengths. In the second Mg2+ site, Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.07 Å) and three longer (2.11 Å) Mg–O bond lengths. S+3.33+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four MgO6 octahedra. The corner-sharing octahedra tilt angles range from 12–45°. There is one shorter (1.47 Å) and three longer (1.48 Å) S–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Mg2+ and one S+3.33+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one S+3.33+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mg2+ and one S+3.33+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mg2+ and one S+3.33+ atom.
