| 摘 要： | Reactions of Zn(NO3)2·6H2O and MNO3(M = Na, K and Rb) with H2mip(H2mip = 5-methylisophthalic acid) in DMF(DMF = N,N′-dimethylformamide) resulted in the formation of novel heterometallic metal-organic frameworks(Me2NH2)[ZnM(mip)2](1: M = Na; 2: M = K; 3: M = Rb, mip = 5-methylisophthalate dianion for 1~3). These complexes belong to the monoclinic system, space group P2/c and have been fully characterized by satisfactory elemental analysis, FT-IR spectra, TGA and single-crystal X-ray diffraction. Single-crystal X-ray diffraction studies reveal that 1~3 are 3D isomorphic structures based on a trinuclear unit {ZnM2(?2-COO)2(?3-COO)2} and exhibit pcu topological net and blue fluorescence.
