摘要
Three metal–organic coordinate complexes based on 3-nitrophthalic acid (H2NPA), namely Cd2(H2O)(OH)2(NPA) (1), Cd2(Im)4(NPA)2 (2) and Cd2(Bim)4(H2O)(NPA)2 (3) (Im = imidazole, Bim = benzimidazole), have been obtained by hydrothermal method and characterized by X-ray single crystal structure determination. Structural analysis reveals that complex 1 exhibits 2D layers constructed by polyhedral aggregates. Complex 2 exhibits a dinuclear cadmium structural unit and assembles by hydrogen bonds into a 2D supramolecular architecture. Complex 3 is assembled by NPA2− into layers of a (3,4)-connected dinodal net topology of (4·52)(4·53·72). The fluorescent properties of complexes 1–3 have been investigated.
