Finding a high nuclearity hybrid framework with novel structure and properties by an environmentally benign approach is a really challenging task. Herein, a green strategy for synthesis of a new inorganic-organic hybrid framework solid has been described. The framework contains silver sulfate clusters with nine different silver ions with shortest silver-silver connectivity. The present compound is the first example of nonanuclear silver sulfate hybrid framework with a new topology. The hybrid solid compound shows a highly active Lewis acidic nature for the various heterogeneous catalytic reactions such as cyanosilylation, ketalization, and esterification with quantitative transformation and recyclability.

Reactions between Zn(NO3)2·6H2O, Na2S2O3, 4,4′-bipyridine (bpy), 1,2-bis(4-pyridyl)ethene (bpe), 1,2-bis(4-pyridyl)ethane (bpa), and 1,3-bis(4-pyridyl)propane (bpp) under solvothermal conditions resulted in four new zinc thiosulfate hybrid compounds. Compound I has four-membered zinc thiosulfate rings connected by the ligand, 1,3-bis(4-pyridyl)propane (bpp) forming a two-dimensional structure. Compounds II-IV have one-dimensional zinc thiosulfate chains connected by the ligands, bpy (II), bpe (III), and bpa (IV) giving rise to three-dimensional structures. All the four-structures exhibit 3-fold interpenetration. Proton conductivity studies indicate reasonable proton mobility at 34 °C and at 98% relative humidity. The compounds also exhibit Lewis acid character and good photocatalytic activity for the decomposition of cationic dyes.
