title: Aqua-(trifluoro-methane-sulfonato)-bis-(1,3,7-trimethyl-purine-2,6-dione)silver(I).
abstract: In the title compound, [Ag(CF(3)SO(3))(C(8)H(10)N(4)O(2))(2)(H(2)O)], the Ag(I) atom is coordinated by two caffeine N atoms and, at longer distances, two O atoms of a coordinated water mol-ecule and the trifluoro-methane-sulfonate anion, resulting in an AgN(2)O(2) seesaw geometry. The caffeine mol-ecules are roughly coplanar [dihedral angle = 5.81 (5)°]. In the crystal, mol-ecules self-assemble into a linear supra-molecular chain along the c axis via O-H⋯O hydrogen bonds involving the coordinated water moledcule and carbonyl O atoms. The packing is consolidated by weak C-H⋯O inter-actions.
