Abstract

By modulating the synthetic strategy based on changing metal salt used in the synthesis, four new metal(II) complexes, [Cu(H 2 O) 3 (MIBA) 2 ]·H 2 O (1), [Ni 2 (H 2 O) 6 (MIBA) 4 ] n (2), [Co(MIBA) 2 ] n (3) and [Zn(MIBA) 2 ] n (4) constructed by 4-(1H-2-methylimidazol-1-yl)benzoic acid (HMIBA) were synthesized under hydrothermal/solvothermal conditions and characterized by single crystal X-ray diffraction, powder XRD, FT-IR, TGA and elemental analysis techniques. Although the four MCPs were constructed by the same semi-rigid imidazolium carboxylate ligand, their structures are quite different . The structural analyses revealed that complex 1 is a discrete mononuclear unit, which are extended to form 3 D supramolecular architectures by hydrogen bonds. Complex 2 features a 1D antenna-like chain, complex 3 exhibit a 2D + 2D → 3D structure, and complex 4 exhibits a 3D → 3D fourfold interpenetrating framework. Furthermore, the antibacterial tests indicated that complex 1 exhibit more excellent bacteriostatic activity than Cu(II) ion and HMIBA ligand, which is more sensitive to E.coli than to S.aureus. The fl uorescent properties and molecular simulation of the complex 4 was also investigated in the solid state at room temperature.
