The material described by Ca(NO3)2 crystallizes in the cubic Pa-3 space group. Ca(1) is bonded to twelve equivalent O(1) atoms to form corner-sharing CaO12 cuboctahedra. N(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a distorted single-bond geometry to two equivalent Ca(1) and one N(1) atom. is represented by the CIF file [CIF]
