CdNO4 crystallizes in the orthorhombic P2_12_12_1 space group. Cd(1) is bonded in a 6-coordinate geometry to one O(3), two equivalent O(2), and three equivalent O(4) atoms. N(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one N(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Cd(1) and one N(1) atom. In the third O site, O(3) is bonded in a distorted L-shaped geometry to one Cd(1) and one N(1) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to three equivalent Cd(1) atoms.
CdNO4 crystallizes in the orthorhombic P2_12_12_1 space group. Cd(1) is bonded in a 6-coordinate geometry to one O(3), two equivalent O(2), and three equivalent O(4) atoms. The Cd(1)-O(3) bond length is 2.48 Å. There is one shorter (2.41 Å) and one longer (2.42 Å) Cd(1)-O(2) bond length. There is one shorter (2.22 Å) and two longer (2.24 Å) Cd(1)-O(4) bond lengths. N(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. The N(1)-O(1) bond length is 1.23 Å. The N(1)-O(2) bond length is 1.32 Å. The N(1)-O(3) bond length is 1.26 Å.
