AgC4H3S(NO)2 crystallizes in the monoclinic P2_1/c space group. Ag(1) is bonded in a 4-coordinate geometry to one N(1), one O(2), and two equivalent O(1) atoms. The Ag(1)-N(1) bond length is 2.37 Å. The Ag(1)-O(2) bond length is 2.24 Å. There is one shorter (2.27 Å) and one longer (2.74 Å) Ag(1)-O(1) bond length. There are four 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 1.49 Å. The C(1)-N(1) bond length is 1.37 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(4), and one S(1) atom. The C(2)-C(4) bond length is 1.48 Å. The C(2)-S(1) bond length is 1.70 Å. In the third C site, C(3) is bonded in a distorted trigonal non-coplanar geometry to one C(1), one H(1), one H(2), and one H(3) atom. The C(3)-H(1) bond length is 1.10 Å. The C(3)-H(2) bond length is 1.10 Å. The C(3)-H(3) bond length is 1.10 Å. In the fourth C site, C(4) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(4)-O(1) bond length is 1.27 Å. The C(4)-O(2) bond length is 1.27 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Ag(1), one C(1), and one N(2) atom. The N(1)-N(2) bond length is 1.31 Å. In the second N site, N(2) is bonded in a water-like geometry to one N(1) and one S(1) atom. The N(2)-S(1) bond length is 1.66 Å. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. S(1) is bonded in an L-shaped geometry to one C(2) and one N(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent Ag(1) and one C(4) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ag(1) and one C(4) atom. Linkers: 4 Cc1nnsc1C([O])=O. Metal clusters: 4 [Ag].
