Two silver(I)-organometallic polymers have been constructed by utilizing the different silver(I) salts and a bowl-shaped calix[4]arene functionalized with tetra-allyl groups on the upper rim (L). Reacted with AgClO4 to afford 1, 1 exhibits a two-dimensional (2D) structure, where tetra-allyl-functionalized calix[4]arene units are linked through Ag–alkene interaction to generate wave-like organometallic chains and further connected by bridging by acetone molecules to afford a 2D network, giving a 2,4,4-net with the point (Schl?fli) symbol {42·82·102}{42·84}2{4}2. Substituting ClO4– by NO3– as the counteranion of silver(I) salt, a three-dimensional organometallic polymer (2) encapsulating solvent molecules in the cavities was generated by connection of 2D inorganic AgNO3 layers and pillared L ligands, which gave a 3,3,4,4-net with the point (Schl?fli) symbol {6·7·8}2{62·7·82·9}2{62·72·92}{62·7}2. In addition, thermogravimetric analysis, luminescent properties, and voltammetric behavior of 1 and 2 also have been investigated. Structural results for these complexes show that the different counteranions play an important role in constructing silver(I)-organometallic polymers with thus flexible tetra-allylcalix[4]arene.
