Materials Data on CaCd(NO3)4 by Materials Project

CaCd(NO3)4 crystallizes in the trigonal P3_121 space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.39–2.57 Å. Cd2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.39–2.68 Å. There are two inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.22 Å) and one longer (1.29 Å) N–O bond length. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.32 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+ atom. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Ca2+, one Cd2+, and one N5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one Cd2+, and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted L-shaped geometry to one Cd2+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+ and one N5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Cd2+ and one N5+ atom.
