Structure diversity of a series of new coordination polymers based on a C3-symmetric tridentate ligand with rosette architecture

Supramolecular assembly of C3-symmetric 4,4′,4″-[1,3,5-benzenetriyltris(carbonylimino)]trisbenzoic acid (H3L) and its ligand behavior toward divalent zinc, cobalt and cadmium ions were investigated. The results exhibit a rosette-type hydrogen-bonded network of the free acid and metal coordination polymers of L3− bearing interesting structural motifs.
