AgC3H2(NO)3 crystallizes in the monoclinic P2_1/c space group. Ag(1) is bonded to two equivalent N(2), one O(1), and one O(3) atom to form distorted corner-sharing AgN2O2 trigonal pyramids. There is one shorter (2.22 Å) and one longer (2.61 Å) Ag(1)-N(2) bond length. The Ag(1)-O(1) bond length is 2.51 Å. The Ag(1)-O(3) bond length is 2.29 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one C(2), one C(3), and one N(1) atom. The C(1)-C(2) bond length is 1.39 Å. The C(1)-C(3) bond length is 1.47 Å. The C(1)-N(1) bond length is 1.39 Å. In the second C site, C(2) is bonded in a distorted linear geometry to one C(1) and one N(2) atom. The C(2)-N(2) bond length is 1.18 Å. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(3), and one O(3) atom. The C(3)-N(3) bond length is 1.33 Å. The C(3)-O(3) bond length is 1.28 Å. There are three inequivalent N sites. In the first N site, N(3) is bonded in a trigonal planar geometry to one C(3), one H(1), and one H(2) atom. The N(3)-H(1) bond length is 1.03 Å. The N(3)-H(2) bond length is 1.02 Å. In the second N site, N(1) is bonded in a trigonal planar geometry to one C(1), one O(1), and one O(2) atom. The N(1)-O(1) bond length is 1.27 Å. The N(1)-O(2) bond length is 1.26 Å. In the third N site, N(2) is bonded in a 3-coordinate geometry to two equivalent Ag(1) and one C(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to one Ag(1) and one N(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one N(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Ag(1) and one C(3) atom. Linkers: 4 N#C[C](C(N)=O)[N+](=O)[O-]. Metal clusters: 4 [Ag].
