Ag2C5HO4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(4), and two equivalent O(2) atoms. The Ag(1)-O(1) bond length is 2.36 Å. The Ag(1)-O(4) bond length is 2.27 Å. There is one shorter (2.35 Å) and one longer (2.46 Å) Ag(1)-O(2) bond length. In the second Ag site, Ag(2) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), and two equivalent O(1) atoms. The Ag(2)-O(3) bond length is 2.24 Å. The Ag(2)-O(4) bond length is 2.45 Å. There is one shorter (2.35 Å) and one longer (2.64 Å) Ag(2)-O(1) bond length. There are five inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(2), one C(3), and one C(4) atom. The C(1)-C(2) bond length is 1.40 Å. The C(1)-C(3) bond length is 1.41 Å. The C(1)-C(4) bond length is 1.49 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(3), and one H(1) atom. The C(2)-C(3) bond length is 1.39 Å. The C(2)-H(1) bond length is 1.09 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to one C(1), one C(2), and one C(5) atom. The C(3)-C(5) bond length is 1.51 Å. In the fourth C site, C(4) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. The C(4)-O(1) bond length is 1.29 Å. The C(4)-O(2) bond length is 1.27 Å. In the fifth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(3), one O(3), and one O(4) atom. The C(5)-O(3) bond length is 1.26 Å. The C(5)-O(4) bond length is 1.28 Å. H(1) is bonded in a single-bond geometry to one C(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ag(1), two equivalent Ag(2), and one C(4) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ag(1) and one C(4) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Ag(2) and one C(5) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Ag(1), one Ag(2), and one C(5) atom. Linkers: 2 [O]C(=O)c1cc(C([O])=O)c(C([O])=O)cc1C([O])=O.
