Abstract
A crystal engineering rationale was employed to generate coordination polymer based metallogels derived from a C3-symmetric tris-amide-tris-carboxylate ligand, namely N,N′,N′′-bis-(4-carboxylate) trimesicamide (L1). Reactions of L1 with various metal salts such as Cd(NO3)2, Cu(NO3)2, Co(NO3)2 and Zn(NO3)2 in pure water resulted in metallogels G1, G2, G3 and G4, respectively. The gels were thermo-irreversible indicating their coordination polymeric nature. Crystallization of L1 and Cd(NO3)2 from a MeOH–water mixture afforded the coordination polymer CP1, the composition of which was established as [{Cd(μ3-L1)(H2O)}·13H2O]3 from single crystal X-ray diffraction. The crystal structure of CP1 revealed the existence of a 3-fold interpenetrated highly undulating (6,3)-network topology having a large solvent accessible area volume. The results clearly supported the crystal engineering rationale, on which the generation of metallogels was based.
