N2 - Four new metal-organic frameworks [Cu2(2,2′-bipy) 2(ox)(H2O)2]·(H2bptc) (1), [Cu(bptc)0.5(phen)(H2O)]·H2O (2), Co2(bptc)(bmb)1.5 (3) and [Cd2(bptc) (bmb)] ·3H2O (4) (H4bptc = 3,3′,4,4′- biphenyltetracarboxylic acid, ox = oxalate, phen = 1,10-phenanthroline, 2,2′-bipy = 2,2′-bipyridine and bmb = 4,4′-bis((1H-imidazol-1- yl)methyl)biphenyl), were obtained by reactions of the corresponding metal salts with H4bptc and N-containing auxiliary ligands and their structures were determined by single-crystal X-ray diffraction. The results reveal that 1 has a 0-D structure consisting of discrete ionic entities, while 2 features a 1-D ladder structure. Additionally, there exist ?-? stacking and intermolecular hydrogen-bonding interactions in 1 and 2, respectively, forming 3-D supramolecular structures. In 3-4, undulating 2-D metal-bptc layer structures are formed with two different coordination modes of bptc carboxylate groups, respectively, which are further extended by bmb into 3-D structures. Magnetic properties of 1 and 3 have been studied. The photoluminescence property of 4 has also been investigated. Moreover, nonlinear optical measurements showed that 4 displayed a second-harmonic-generation (SHG) response of 0.7 times of that for urea.
