Materials Data on VTe(NO4)2 by Materials Project
VNTeO7NO crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four nitroxyl molecules and one VNTeO7 framework. In the VNTeO7 framework, V4+ is bonded to four O2- atoms to form distorted VO4 tetrahedra that share corners with two equivalent TeO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.62–2.13 Å. N4+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.19 Å. Te4+ is bonded to five O2- atoms to form distorted TeO5 trigonal bipyramids that share corners with two equivalent VO4 tetrahedra and an edgeedge with one TeO5 trigonal bipyramid. There are a spread of Te–O bond distances ranging from 1.82–2.02 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a single-bond geometry to one V4+ and one O2- atom. The O–O bond length is 2.88 Å. In the third O2- site, O2- is bonded in a single-bond geometry to one Te4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one V4+ and one Te4+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one V4+, one Te4+, and one O2- atom. The O–O bond length is 3.13 Å. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two O2- atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one N4+ atom.
