通过Li(TCNQ)分别与PbCl2和Zn(TPP)2Cl2(TPP=三苯基膦)反应，合成了两个7，7，8，8-四氰基二甲烷(TCNQ)Pb2+和Zn2+的配合物：{[Pb2(TCNQ)3(H2O)6](TCNQ)}n(1)和Li[Zn2(TCNQ)5(H2O)6]·[Zn(TCNQ)2(H2O)4]·6H2O(2)。单晶X射线衍射分析表明，配合物1具有三维网状结构，而配合物2具有0D结构，其中中性分子[Zn(TCNQ)2(H2O)4]在晶体中结晶。TCNQ与金属离子的灵活配位方式对这种新型的三维结构和独特的零维离子结构的形成以及TCNQ分子通过TCNQ金属络合物之间的π-π堆积作用适应于一维柱起着至关重要的作用。配合物1和2的循环和差示脉冲伏安图表明，在CH3CN的电化学窗口内发生了可逆单电子氧化和单电子还原。考察了它们的电化学HOMO-LUMO能隙和可逆性。
Two 7,7,8,8-tetracyanoquinodimethane (TCNQ) Pb2+and Zn2+complexes, namely, {[Pb2(TCNQ)3(H2O)6](TCNQ)}n(1) and Li[Zn2(TCNQ)5(H2O)6]·[Zn(TCNQ)2(H2O)4]·6H2O (2) have been synthesized by the reactions of Li(TCNQ) with PbCl2and Zn(TPP)2Cl2(TPP = Triphenylphosphine), respectively. Single-crystal X-ray diffraction analysis reveals that complex1features a 3D network structure and complex2features a 0D structure in which a neutral molecule of [Zn(TCNQ)2(H2O)4] crystallizes in the crystal. The flexible coordination modes of TCNQ and the metal ions play essential roles on the formation of the novel 3D structures and the unique 0D ionic structure as well as the TCNQ molecules adapt in one-dimensional column of TCNQ through π–π stacking interactions among the TCNQ metal complexes. Cyclic and differential pulse voltammograms for complexes1and2show the reversible one-electron oxidation and one-electron reduction within the electrochemical window of CH3CN. Their electrochemical HOMO–LUMO gap and reversibility are examined.
