Materials Data on La2Mg3H48(NO5)12 by Materials Project

Abstract

(Mg(H2O)6)3(La(NO3)6)2(H2O)6 is Brookite-derived structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of nine magnesium;hexahydrate molecules, eighteen water molecules, and six La(NO3)6 clusters. In each La(NO3)6 cluster, La is bonded in a cuboctahedral geometry to twelve O atoms. There are a spread of La–O bond distances ranging from 2.67–2.71 Å. There are two inequivalent N sites. In the first N site, N is bonded in a trigonal planar geometry to three O atoms. There is one shorter (1.24 Å) and two longer (1.28 Å) N–O bond length. 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 1.24–1.29 Å. There are six inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one La and one N atom. In the second O site, O is bonded in a distorted single-bond geometry to one La and one N atom. In the third O site, O is bonded in a single-bond geometry to one N atom. In the fourth O site, O is bonded in a distorted single-bond geometry to one La and one N atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one La and one N atom. In the sixth O site, O is bonded in a single-bond geometry to one N atom.
