Ag2C2SO7(CH2)2(CNH4)2SO3 crystallizes in the monoclinic P2_1 space group. The structure is zero-dimensional and consists of four 02329_fluka molecules, four methylammonium molecules, two sulfur trioxide molecules, and two Ag2C2SO7 clusters. In each Ag2C2SO7 cluster, there are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted linear geometry to one O(3) and one O(7) atom. The Ag(1)-O(3) bond length is 2.17 Å. The Ag(1)-O(7) bond length is 2.20 Å. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one O(10), one O(6), and one O(8) atom. The Ag(2)-O(10) bond length is 2.22 Å. The Ag(2)-O(6) bond length is 2.46 Å. The Ag(2)-O(8) bond length is 2.26 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(10) and one O(7) atom. The C(1)-O(10) bond length is 1.26 Å. The C(1)-O(7) bond length is 1.27 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(8) atom. The C(2)-O(3) bond length is 1.27 Å. The C(2)-O(8) bond length is 1.26 Å. S(2) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(6) atom. The S(2)-O(1) bond length is 1.48 Å. The S(2)-O(2) bond length is 1.48 Å. The S(2)-O(6) bond length is 1.47 Å. There are seven inequivalent O sites. In the first O site, O(10) is bonded in a bent 120 degrees geometry to one Ag(2) and one C(1) atom. In the second O site, O(7) is bonded in a bent 120 degrees geometry to one Ag(1) and one C(1) atom. In the third O site, O(1) is bonded in a single-bond geometry to one S(2) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one S(2) atom. In the fifth O site, O(3) is bonded in a bent 120 degrees geometry to one Ag(1) and one C(2) atom. In the sixth O site, O(8) is bonded in a bent 120 degrees geometry to one Ag(2) and one C(2) atom. In the seventh O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Ag(2) and one S(2) atom. Linkers: 4 [O]C(=O)[C@H](CS([O])([O])[O])[NH3]. Metal clusters: 4 [Ag].
