摘      要：Two pyrazole-based zinc(Ⅱ) metal-organic frameworks,[Zn_(4)(PDC)_(2)(BDC)(H_(2)O)_(2)]_(n) (compound 1,PDC=1H-pyrazole-3,5-dicarboxylic acid,BDC=benzene-1,4,-dicarboxylic acid) and[Zn_(3)(PDC)_(2)(BPY)_(3)(H_(2)O)_(2)]_(n)(compound 2,BPY=4,4-bipyridine),were synthesized and characterized by X-ray diffraction,elemental analysis,thermogravimetric analysis,infrared and fluorescence *** 1 crystallizes in space group Pna2_(1) with a=14.325(3),b=10.004(2),c=16.454(3)Å,V=2357.8(8)Å^(3),Z=4,M_(r)=821.83,D_(c)=2.298 g·cm^(-3),F(000)=1608,GOOF=1.163,the final R=0.0218 and w R=0.0686 for 5150 observed reflections with I2σ(I).Compound 2crystallizes in monoclinic space group C2/c with a=17.034(2),b=11.6313(9),c=11.7608(13)Å,V=2034.9(4)Å^(3),Z=2,Mr=1006.91,D_(c)=1.643 g·cm^(-3),F(000)=1020,GOOF=1.084,the final R=0.0320 and wR=0.0768 for 2435 observed reflections with I2σ(I).
