Materials Data on Te(NO3)2 by Materials Project

Te(NO3)2 crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two Te(NO3)2 ribbons oriented in the (0, 1, 0) direction. N4+ is bonded in a distorted single-bond geometry to three O2- atoms. There is one shorter (1.14 Å) and two longer (2.05 Å) N–O bond length. Te4+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Te–O bond lengths are 1.89 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one N4+ and one Te4+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N4+ atom.

Materials Data on Te2NO6 by Materials Project

N2(TeO3)4 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of four ammonia molecules and two TeO3 sheets oriented in the (0, 0, 1) direction. In each TeO3 sheet, there are two inequivalent Te sites. In the first Te site, Te is bonded to five O atoms to form distorted corner-sharing TeO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 39–41°. There are a spread of Te–O bond distances ranging from 1.79–1.97 Å. In the second Te site, Te is bonded to six O atoms to form TeO6 octahedra that share corners with two equivalent TeO6 octahedra and corners with four equivalent TeO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 49°. There is three shorter (1.95 Å) and three longer (1.96 Å) Te–O bond length. There are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Te atom. In the second O site, O is bonded in a bent 120 degrees geometry to two equivalent Te atoms. In the third O site, O is bonded in a bent 150 degrees geometry to two Te atoms. In the fourth O site, O is bonded in a bent 150 degrees geometry to two Te atoms.
