Synthesis, structure, magnetism and antibacterial properties of a 2-D nickel(II) metal-organic framework based on 3-nitrophthalic acid and 4,4 '-bipyridine

A 2-D nickel(II) mixed-ligand metal-organic framework [Ni(NPTA)(4,4'-bipy)(H2O)](n) (1) was synthesized by reaction of 3-nitrophthalic acid (H(2)NPTA) and 4,4'-bipyridine (4,4'-bipy) with Ni(II) under hydrothermal condition and characterized by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction analysis. Compound 1 possesses a 2-D layer structure constructed from dinuclear nickel(II) building blocks in which two crystallographically equivalent Ni ions are bridged by two NPTA ligands. Furthermore, the layers are connected into 3-D supramolecular network by hydrogen bonds. The magnetism and antibacterial activity of 1 were investigated.
