A 3-D silver(I) polymer with 5,6-dihydro-1,4-dithiin-2,3-dicarboxylate ligand, showing an unusual 6-connected (412.63)2(49.66) topology

The in situ reaction of AgClO4·6H2O with 5,6-dihydro-1,4-dithiin-2,3-dicarboxylic anhydride in the presence of lithium hydroxide afforded a photoluminescent three-dimensional (3-D) AgI coordination polymer, [Ag2(L)]∞ (1), which exhibited an unusual trinodal 6-connected (412.63)2(49.66) topological net (L = 5,6-dihydro-1,4-dithiin-2,3-dicarboxylate). Moreover, the luminescent/thermal properties of 1 have also been briefly investigated.
