摘　　要：Reactions of Zn（NO3）E＇6H20 and MNO3 （M = Na, K and Rb） with HEmip （HEmip = 5-methylisophthalic acid） in DMF （DMF = N,N＇-dimethylformamide） resulted in the formation of novel heterometallic metal-organic frameworks （MeENHE）[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 PE/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 {ZD.ME（/d2-COO）E（μ3- COO）E} and exhibitpcu topological net and blue fluorescence.Reactions of Zn（NO3）E＇6H20 and MNO3 （M = Na, K and Rb） with HEmip （HEmip = 5-methylisophthalic acid） in DMF （DMF = N,N＇-dimethylformamide） resulted in the formation of novel heterometallic metal-organic frameworks （MeENHE）[ZnM（mip）2] （1： M = Na; 2： M = K; 3： M = Rb, mip = 5-methylisophthalate dianion for 1-3）.
