The material structure described by Cu(NO3)2 crystallizes in the orthorhombic Pmn2_1 space group. Cu(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(5), and one O(7) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one O(6) and two equivalent O(3) atoms. In the second N site, N(2) is bonded in a trigonal planar geometry to one O(2), one O(5), and one O(7) atom. In the third N site, N(3) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(1) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one N(3) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one N(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one N(1) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one N(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Cu(1) and one N(2) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one N(1) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one N(2) atom. is represented by the CIF card [CIF]
