在水热条件下,分别用过渡金属离子Zn(Ⅱ)和Co(Ⅱ)与混合手性羧酸和含氮配体反应,合成了2个手性金属-有机配位聚合物[M(D-cam)(H2mbdpz)]n[M=Zn(1),Co(2);D-H2cam=D-(+)-樟脑酸;H2mbdpz=4,4'-亚甲基二(3,5-二甲基吡唑)].通过单晶X射线衍射、粉末X射线衍射、元素分析、热重分析及荧光分析对其结构、组成和性质进行了表征.单晶结构分析表明,配合物1和2是异质同晶的手性三维开放骨架结构,具有单节点三连接的ThSi2型网络拓扑结构.
Two new homochiral metal-organic coordination polymers[M(D-cam)(H2mbdpz)]n[M=Zn(complex 1),Co(complex 2);D-H2cam=D-(+)-camphoric acid,H2mbdpz=4,4′-methylenebis(3,5-dime-thylpyrazole)] were prepared by mixing ligands with corresponding transition metal ions under hydrothermal conditions.The complexes were characterized by means of single-crystal X-ray diffraction,elemental analysis,thermograrimetri analysis(TGA),powder X-ray diffraction(XRD) and photoluminescent(PL) spectrometry.X-ray crystallography reveals that complexes 1 and 2 are isomorphous and homochiral,exhibiting the three-dimensional open structure with a ThSi2 type of uninodal 3-connected networks.
