NaCNO5(CH2)2C2NH5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure consists of eight 02329_fluka molecules and four dimethylazanium molecules inside a NaCNO5 framework. In the NaCNO5 framework, Na(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(5), two equivalent O(3), and two equivalent O(4) atoms. The Na(1)-O(1) bond length is 2.33 Å. The Na(1)-O(2) bond length is 2.29 Å. The Na(1)-O(5) bond length is 2.47 Å. There is one shorter (2.52 Å) and one longer (2.83 Å) Na(1)-O(3) bond length. Both Na(1)-O(4) bond lengths are 2.52 Å. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(2) bond length is 1.25 Å. N(2) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. The N(2)-O(3) bond length is 1.26 Å. The N(2)-O(4) bond length is 1.28 Å. The N(2)-O(5) bond length is 1.27 Å. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Na(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one N(2) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent Na(1) and one N(2) atom. In the fifth O site, O(5) is bonded in a distorted L-shaped geometry to one Na(1) and one N(2) atom. Linkers: 4 [O]C(=O)[C@@H]1CCC[NH2]1 ,4 [O][N+](=O)[O-]. Metal clusters: 4 [Na].
