AgC5H5(NO)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four AgC5H5(NO)2 clusters. Ag(1) is bonded in a distorted bent 150 degrees geometry to one N(2) and one O(1) atom. The Ag(1)-N(2) bond length is 2.14 Å. The Ag(1)-O(1) bond length is 2.22 Å. There are five inequivalent C sites. In the first C site, C(3) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(3) atom. The C(3)-N(1) bond length is 1.36 Å. The C(3)-N(2) bond length is 1.33 Å. The C(3)-H(3) bond length is 1.08 Å. In the second C site, C(4) is bonded in a distorted trigonal non-coplanar geometry to one N(1) and two equivalent H(4,5) atoms. The C(4)-N(1) bond length is 1.45 Å. Both C(4)-H(4,5) bond lengths are 1.10 Å. In the third C site, C(5) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(5)-O(1) bond length is 1.28 Å. The C(5)-O(2) bond length is 1.27 Å. In the fourth C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one N(1), and one H(1) atom. The C(1)-C(2) bond length is 1.38 Å. The C(1)-N(1) bond length is 1.38 Å. The C(1)-H(1) bond length is 1.08 Å. In the fifth C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(2), and one H(2) atom. The C(2)-N(2) bond length is 1.38 Å. The C(2)-H(2) bond length is 1.08 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(4) atom. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one Ag(1), one C(2), and one C(3) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(4,5) is bonded in a single-bond geometry to one C(4) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Ag(1) and one C(5) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(5) atom.
