Materials Data on ErCoH8C6(N3O2)2 by Materials Project

Abstract

CoErC6H4(N3O)2(H2O)2 crystallizes in the orthorhombic Cmcm space group. The structure is zero-dimensional and consists of four cobalt molecules, eight water molecules, and four ErC6H4(N3O)2 clusters. In each ErC6H4(N3O)2 cluster, Er3+ is bonded in a 8-coordinate geometry to six N3- and two equivalent O2- atoms. There are four shorter (2.45 Å) and two longer (2.47 Å) Er–N bond lengths. Both Er–O bond lengths are 2.30 Å. There are two inequivalent C+2.33+ sites. In the first C+2.33+ site, C+2.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the second C+2.33+ site, C+2.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted bent 150 degrees geometry to one Er3+ and one C+2.33+ atom. In the second N3- site, N3- is bonded in a distorted linear geometry to one Er3+ and one C+2.33+ atom. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. O2- is bonded in a distorted water-like geometry to one Er3+ and two equivalent H1+ atoms.
