摘要
以多氮杂环配体二吡啶[3,2-a:2',3'-c]并吩嗪(DPPZ)和[2,3-f]吡嗪并[1,10]菲罗啉(Pyphen)为配体,采用水热法合成了两个配合物[Zn(DPPZ)2SO4]·2H2O(1)和[Cd(Pyphen)2Cl2](2),利用元素分析和单晶X-射线衍射对其结构进行了表征.分析结果表明,配合物(1)和(2)都属于单斜晶系,空间群都为C2/c.配合物1的晶胞参数为:a=17.500 7(9),b=7.234 4(5),c=23.182 2(14),β=94.942(5)°,V=2 924.1(3)3,Z=4;配合物(2)的晶胞参数为:a=8.509 8(17),b=12.524(3),c=22.683(5),β=95.31(3)°,V=2 407.0(8)3,Z=4.配合物(1)和(2)均为零维结构单元,配合物(1)的单元之间通过π-π堆积作用形成二维层状结构,层与层之间通过氢键作用形成三维超分子结构.配合物(2)的配位单元之间通过Pyphen配体的π-π堆积作用构筑成一个二维超分子结构.
Two different complexes[Zn（DPPZ）2 SO4 ]·2（H2 O）（1）and[Cd（Pyphen）2 Cl2 ]（2）based on the multi-nitrogen heterocyclic ligands dipyrido[3,2-a：2＇,3＇-c]phenazine（DPPZ）or pyrazino[2,3-f][1,10] phenanthroline have been synthesized under hydrothermal conditions and characterized by elemental analysis and single-crystal X-ray diffraction. Two complexes crystallizes in monoclinic crystal space group C 2 / c,with complex （1）a = 17. 500 7（9）？,b = 7. 234 4（5）？,c = 23. 182 2（14）？,β = 94. 942（5）°,V = 2 924. 1（3）？3 ,Z = 4 and complex（2）a = 8. 509 8（17）？,b = 12. 524（3）？,c = 22. 683（5）？,β = 95. 31（3）°,V = 2 407. 0（8） ？3 ,Z = 4. The structure of the title compounds（1）and（2）is mononuclear 0D unit. In complex（1）,a 2D layer structure is formed through the π-π interactions between the adjacent independent units,and the layers are linked through hydrogen bonds to form a 3D supramolecular structure. Complex（2）is stacked through π-π interactions between the Pyphen ligands to form a 2D supramolecular structure.
