Cu(N2O3)2 is Protactinium structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of four copper;azanide;nitric acid molecules. Cu(1) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent O(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a single-bond geometry to one Cu(1) 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(3) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to one N(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one N(2) atom. In the third O site, O(2) is bonded in a single-bond geometry to one N(2) atom.
