The material structure described by CaCd(NO3)4 crystallizes in the trigonal P3_121 space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. Cd(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to one O(3) and one O(6) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one Ca(1) atom. In the second O site, O(5) is bonded in a distorted T-shaped geometry to one Ca(1), one Cd(1), and one N(2) atom. In the third O site, O(6) is bonded in a 3-coordinate geometry to one Ca(1), one Cd(1), and one N(1) atom. In the fourth O site, O(1) is bonded in a distorted L-shaped geometry to one Cd(1) and one N(2) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to one Ca(1) and one N(2) atom. In the sixth O site, O(3) is bonded in a single-bond geometry to one Cd(1) and one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
