Materials Data on CeMg(N3O13)2 by Materials Project
MgO8Ce(NO3)6 is alpha Niobium phosphide-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two Ce(NO3)6 clusters and two MgO8 clusters. In each Ce(NO3)6 cluster, Ce is bonded in a cuboctahedral geometry to twelve O atoms. There are a spread of Ce–O bond distances ranging from 2.53–2.62 Å. There are three inequivalent N sites. In the first N site, N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.23–1.29 Å. In the second N site, N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.24–1.28 Å. In the third N site, N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.24–1.29 Å. There are nine inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one Ce and one N atom. In the second O site, O is bonded in a single-bond geometry to one N atom. In the third O site, O is bonded in a distorted single-bond geometry to one Ce and one N atom. In the fourth O site, O is bonded in a distorted single-bond geometry to one Ce and one N atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one Ce and one N atom. In the sixth O site, O is bonded in a single-bond geometry to one N atom. In the seventh O site, O is bonded in a distorted water-like geometry to one Ce and one N atom. In the eighth O site, O is bonded in a single-bond geometry to one N atom. In the ninth O site, O is bonded in a distorted single-bond geometry to one Ce and one N atom. In each MgO8 cluster, Mg is bonded in an octahedral geometry to six O atoms. There are a spread of Mg–O bond distances ranging from 2.08–2.22 Å. There are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.24 Å. In the second O site, O is bonded in a 2-coordinate geometry to one Mg and one O atom. The O–O bond length is 1.30 Å. In the third O site, O is bonded in a 2-coordinate geometry to one Mg and one O atom. In the fourth O site, O is bonded in a distorted bent 120 degrees geometry to one Mg and one O atom.
