Ancillary ligand-assisted assembly of C3-symmetric 4,4′,4″-nitrilotribenzoic acid with divalent Zn2+ ions: Syntheses, topological structures, and photoluminescence properties

Supramolecular assembly of 4,4′,4′′-nitrilotribenzoic acid and its ligand behavior toward Zn2+ were investigated, which exhibit two polymorphs of the free acid and four metal coordination polymers bearing interesting structural motifs. 263
