New Zn(Ⅱ)/M(I) (M=Na, K and Rb) Metal-organic Frameworks Based on 5-Methylisophthalic Acid Ligand: Syntheses, Structures and Fluorescent Property
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(μ2-COO)2(μ3-COO)2} and exhibit pcu topological net and blue fluorescence.
