Controllable assembly of silver(I) complexes by variations of the carboxyl configuration: From a 2-D (45·6)2(418·610) layer to an unusual 3-D 5-connected self-penetrating (44·66)2 network

The reaction of AgClO4·6H2O with (+/−)-trans-epoxysuccinic acid (H2tes) in the presence of 2,6-dimethylpyridine afforded a three-dimensional (3-D) AgI coordination polymer [Ag2(tes)]∞ (1), which exhibits an unusual 5-connected self-penetrating (44·66)2 topological net (tes = (+/−)-trans-epoxysuccinate). Comparison of the structural differences with our relevant finding, a two-dimensional (2-D) (4,8)-connected (45·6)2(418·610) coordination polymer [Ag4(ces)2]∞ (S1) (ces = cis-epoxysuccinate), suggests that the carboxyl configuration on the ternary ring backbone of H2tes or H2ces ligand plays an important role in the construction of coordination networks.
