Materials Data on VP2(NO4)2 by Materials Project
VP2(NO4)2 crystallizes in the tetragonal P4bm space group. The structure is two-dimensional and consists of one VP2(NO4)2 sheet oriented in the (0, 0, 1) direction. V4+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with four equivalent PO4 tetrahedra. There is one shorter (1.61 Å) and four longer (2.03 Å) V–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.50–1.66 Å. N1+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.34 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one V4+ and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent P5+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one V4+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one N1+ atom.
