摘要(Abstract)：

采用水热法合成了一个结构新颖的锌配合物Zn(Him)2(bna)21(Him=咪唑;Hnba=5-溴烟酸),并用X射线粉末衍射、红外光谱、热重分析及X射线单晶衍射进行了结构表征.研究结果表明,配合物属于三斜晶系,空间群P-1,晶胞参数为:a=9.273(2) ,b=10.971(2) ,c=11.162(2) ,α=97.4(1)°,β=105.1(1)°,γ=100.0(1)°,V=1 061.4(4) 3,C18H14Br2N6O4Zn,Mr=603.54,Dc=1.888g·cm-3,μ=4.960mm-1,F(000)=592,Z=2,最终偏离因子[I>2σ(I)]R1=0.048 3,wR2=0.106 1;在配位物晶体中,中心锌离子形成了畸变的四面体配位模式,分子间通过N-H…O氢键作用沿b方向形成了一维超分子链.并对配合物1的荧光性质进行了测试.CCDC1024450.
