摘要
3,4-吡唑二甲酸(H3pdc)与Zn(NO3)2·6H2O在不同的条件下反应制得了2个新的配合物:[Zn(H2pdc)2(H2O)2]·2H2O(1)和[Zn2(Hpdc)2(H2O)6]·2H2O(2)。X射线衍射分析表明,1和2分别是单核和双核结构。H3pdc部分脱质子后的阴离子配体在1和2中采用的是N,O-螯合(H2pdc-)以及μ2-κN,O∶κN桥联(Hpdc2-)配位模式。在这2个配合物中,相邻的零维组分通过分子间氢键(O-H…O,N-H…O和C-H…O)作用形成三维超分子结构。此外我们还研究了配合物1和2的热稳定性和荧光性能。
Treatment of H3pdc with Zn(NO3)2·6H2O under different reaction conditions afforded two complexes,[Zn(H2pdc)2(H2O)2]·2H2O(1)and[Zn2(Hpdc)2(H2O)6]·2H2O(2)(H3pdc=3,4-pyrazoledicarboxylic acid).X-ray diffraction analyses reveal that 1 and 2 contain mono-and dinuclear Zn(Ⅲ)components,respectively.The partly deprotonated H3pdc ligand anions in 1 and 2 adopt N,O-chelating fashion(H2pdc-)andμ2-κN,O∶κN′bridging mode(Hpdc2-),respectively.In both complexes,the adjacent zero-dimensional components are connected by intermolecular hydrogen bonds(O-H…O,N-H…O and C-H…O)to form a three-dimensional supramolecular architecture.The thermal and luminescent properties of complexes 1 and 2 have also been investigated.CCDC:1944037,1;1944038,2.
