AgC4NH4O3 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two AgC4NH4O3 clusters. Ag(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. The Ag(1)-O(1) bond length is 2.53 Å. The Ag(1)-O(2) bond length is 2.20 Å. The Ag(1)-O(3) bond length is 2.25 Å. There are four inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(4)-O(2) bond length is 1.27 Å. The C(4)-O(3) bond length is 1.27 Å. In the second C site, C(1) is bonded in a distorted trigonal non-coplanar geometry to one N(1) and two equivalent H(1,2) atoms. The C(1)-N(1) bond length is 1.46 Å. Both C(1)-H(1,2) bond lengths are 1.10 Å. In the third C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one O(1) atom. The C(2)-N(1) bond length is 1.35 Å. The C(2)-O(1) bond length is 1.25 Å. In the fourth C site, C(3) is bonded in a distorted trigonal non-coplanar geometry to one N(1), one H(3), and one H(4) atom. The C(3)-N(1) bond length is 1.45 Å. The C(3)-H(3) bond length is 1.10 Å. The C(3)-H(4) bond length is 1.10 Å. N(1) is bonded in a trigonal planar geometry to one C(1), one C(2), and one C(3) atom. There are three inequivalent H sites. In the first H site, H(1,2) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(3) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Ag(1) and one C(2) 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. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ag(1) and one C(4) atom. Linkers: 2 [O]C(=O)CN1CC(=O)N(CC([O])=O)CC1=O ,2 [O]C(=O)[CH]N1CC(=O)N(CC([O])=O)CC1=O.
