Ag16(SO4)8 and Ag4(SO4)2 SBUs that are interconnected by L1 ligands, whereas 2 has a much denser network constructed from Ag10(SO4)5 SBUs and L2 linkers. To our knowledge, the Ag16(SO4)8 cluster core found in 1 is the largest sulfate-based polynuclear SBU in coordination polymers, and the 14-connected Ag10(SO4)5 in 2 is the highest-connectivity Ag(I) cluster SBU reported to date. These two complexes were

are linked by ligands L to furnish a double-bridged chain and a ladder-like structure, respectively. Complexes 5–7 are assembled with dicarboxylate spacers and flexible L, which link Ag2 units to form a 2D slablike architecture in 5, and 3D coordination frameworks in 6 and 7. In addition, the effect of the carboxylate ligands on the ligation behavior of L and supramolecular assembly of the series of

synthesized and characterized by X-ray crystallography. Isomorphous complexes 1 and 2 feature an infinite coordination chain composed of (C2)2Ag15 clusters alternatively linked by L1 or L2 ligands; weak intermolecular C–H···F hydrogen bonding between adjacent infinite chains results in a three-dimensional supramolecular network. Complex 3 exhibits a coordination layer structure composed of (tBuC2)2Ag7
