Materials Data on V3(NO4)2 by Materials Project

V3(NO4)2 crystallizes in the tetragonal P4bm space group. The structure is two-dimensional and consists of one V3(NO4)2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent V+4.67+ sites. In the first V+4.67+ site, V+4.67+ is bonded to five O2- atoms to form distorted corner-sharing VO5 trigonal bipyramids. There is one shorter (1.62 Å) and four longer (1.91 Å) V–O bond length. In the second V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one VO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.76–1.97 Å. N1+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.22 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one V+4.67+ and one N1+ atom. In the third O2- site, O2- is bonded in a linear geometry to two equivalent V+4.67+ atoms. In the fourth O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom.

Materials Data on V3(NO4)2 by Materials Project

V3O8N2 crystallizes in the tetragonal P4bm space group. The structure is two-dimensional and consists of four ammonia molecules and one V3O8 sheet oriented in the (0, 0, 1) direction. In the V3O8 sheet, there are two inequivalent V+4.67+ sites. In the first V+4.67+ site, V+4.67+ is bonded to five O2- atoms to form distorted corner-sharing VO5 trigonal bipyramids. There is one shorter (1.61 Å) and four longer (1.90 Å) V–O bond length. In the second V+4.67+ site, V+4.67+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one VO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of V–O bond distances ranging from 1.65–1.81 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one V+4.67+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two V+4.67+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent V+4.67+ atoms.
