Research topics from publications: Effect of Coordinated Solvent Molecules on Metal Coordination Sphere and Solvent-Induced Transformations; Reaction-determined assemblies of 0D to 3D complexes: structural diversities and luminescence properties. Representative work: Four similar Mn(II) metal–organic frameworks (MOFs), {[Mn2(nbtc)(H2O)2(S)]·S·0.5H2O}n [S = DMF (1), DMA (2), NMP (3), DEF (4)] (DMF = N,N′-dimethylformamide, DMA = N,N′-dimethylacetamide, NMP = N-methyl-2-pyrrolidinone, DEF = N,N′-diethylformamide), have been assembled solvothermally from the nitro and carboxyl doubly functionalized ligand 6,6′-dinitro-2,2′,4,4′-biphenyl tetracarboxylic acid (H4nbtc) and characterized by single-crystal X-ray diffraction, elemental analyses, infrared spectroscopy, thermogravimetric analyses, and powder X-ray diffraction. All MOFs exhibit unique three-dimensional double-walled open-frameworks with one-dimensional parallelogram channels and have guest/coordinat Reaction-determined assemblies of 6,6′-dinitrobiphenyl-2,2′,4,4′-tetracarboxylic acid (H4nbtc), various N-donor ligands and transition metal ions produce ten complexes, namely, [Zn2(nbtc)(bpa)·H2O]n (1), [Zn2(nbtc)(bpe)·H2O]n (2), [Zn2(nbtc)(2,2′-dpy)]n (3), Zn(H3nbtc)(phen)2 (4), {(H3O)2[Cd3(nbtc)2(H2O)3]·5H2O}n (5), [Cd2(nbtc)(ndpy)·0.5H2O]n (6), [Ag2(H2nbtc)(bpp)]n (7), [Co2(nbtc)(phen)2(H2O)2]n (8), [Ni2(nbtc)(phen)2(H2O)2]n (9) and Co(H2nbtc)(phen)2·2H2O (10) (bpa = 1,2-bis(4-pyridyl)ethane, bpe = 1,2-di(4-pyridyl)ethylene, bpp = 1,3-bis(4-pyridyl)propane, 2,2′-dpy = 2,2′-dipyridyl, phen = 1,10-phenanthroline, ndpy = 2-pyridinamine).
