摘　　要：在水热条件下,以(PTCP=2-苯基-1,3,7,8-四氮杂环戊烷[l]-邻菲罗啉)为配体构筑了两个过渡金属配合物[Ni2(PTCP)4(SO4)(H2O)3][(SO4)(H2O)4.5](1)和[Fe(PTCP)3][(SO4)(H2O)7](2).X-射线单晶衍射分析表明这两个化合物都是由PTCP、硫酸根和水簇之间通过氢键从零维低聚物扩展形成三维超分子交叉网格结构.在配合物1中,可以观察到自组装的基于八水簇的一维梯形氢键链,通过PTCP配体之间的π-π堆积相互作用使结构进一步扩展形成二维网格的非共价键合的平面.在配合物2中,形成了基于(H2O)7簇的右手螺旋氢键链,进一步通过[Fe(Phen)]2+单元形成了三维超分子结构.实验结果表明,通过将合适的配体、金属盐以及硫酸根等无机阴离子引入到配合物中来捕获溶剂水,能够产生强有力的非共价键体系.Two new complexes[Ni2（PTCP）4（SO4）（H2O）3][（SO4）（H2O）4.5]（1） and [Fe（PTCP）3][（SO4）（H2O）7]（2）（PTCP=2-phenyl-1,3,7,8-tetraazacyclopenta[l]phenanthrene） have been hydrothermally synthesized and characterized via X-ray single-crystal diffraction.Structural analyses revealed that both complexes are 0D oligomers which further propagate to 3D supramolecular crossover networks through the hydrogen bond between PTCP,sulfate anions and water clusters.A self-assembled 1D ladder-like hydrogen bonding chain based on （H2O）8 clusters is observed in （1）,which is further extended into a 2D grid-like non-covalent bonding plane through π-π stacking interactions between the PTCP ligands.In （2）STBZ,right-handed helical hydrogen bonding chains based on the （H2O）7 clusters are formed which further lead to the formation of a 3D supramolecular architecture through the[Fe（Phen）]2＋（Phen=phenanthroline） units.The results clearly indicate that complex by selecting the appropriate ligands and metals,the inorganic anions such as sulfate can be introduced into the polymer to achieved the captured the solvent water , which can create a powerfu1 non-cova1ent bonds system.
