摘      要：A three-dimensional(3D)zinc metal-organic framework(MOF),Zn4(μ4-O)(bcd)3(complex 1)has been synthesized by using 1-[bis(4-carboxylphenyl)methyl]-1,3-diazole(H2 bcd)and Zn(NO3)2·6 H2O under hydrothermal *** structure has been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses,IR spectra,powder X-ray diffraction(PXRD)and thermogravimetric analyses(TGA).Single-crystal X-ray diffraction analyses reveal that complex 1 crystallizes in trigonal system,space group R3 with a=23.0521(6),b=23.0521(6),c=15.3326(6)A,γ=120°,V=7056.2(4)A^3,Z=6,C54H36N6O13Zn4,Mr=1242.37,Dc=1.754 g/cm^3,F(000)=3756,the final R=0.0411 and wR=0.1007 for 2743 observed reflections(I2σ(I)).Complex 1 consists of a 3D network constructed by four nuclear clusters Zn4(μ4-O)(COO)6 N3 and the ***,1 exhibits strong luminescent emission in solid state at room temperature and could be used as a qualitative fluorescence enhancing sensor for ammonia vapor in air.
