Synthesis,Crystal Struture and Properties of Three-dimensional Supramolecular Monoclear Lead Complex [Pb(m-abc)_2(phen)]

水热条件下,合成了具有三维超分子结构的单核Pb(II)的含混合配体化合物[Pb(m-abc)_2(phen)](m-abc=间氨基苯甲酸,phen=1,10-邻菲啰啉),并通过多种手段如X-射线单晶衍射、室温固体红外、元素分析和热重等对其进行了表征。X-射线单晶衍射的分析结果表明,化合物结晶于单斜晶系P2_1/c空间群,晶胞参数:a=0.80415(10)nm,b=1.52987(19)nm,c=1.8330(2)nm,β=98.251(2)°,V=2.2317(5)nm^3,Z=4。化合物中的Pb离子采用五配位模式Pb O_3N_2,构成扭曲的四方锥构型。其内部通过各种N-H…O弱相互作用形成超分子结构。

The mononuclear containing mixed-donor ligands Pb （ II ） complex [ Pb （ m-abe ） 2 （ phen ） J （phen = 1, 10-phenanthroline, m-abe = m-aminobenzenecarboxylate ） with three-dimensional supramolecular structure was synthesized under hydrothermal conditions. It was characterized by X-ray crystal diffraction, IR, TGA and elemental analysis methods. The characterization results of X-ray single crystal diffraction indicate that the title complex crystallizes in rnonoelinic system with space group P21/c. The unit cell parameters include a = 0.80415 （10） nm, b = 1. 52987 （19） nm, c = 1. 8330 （2） nm,β = 98.251 （2） °, V = 2.2317 （ 5 ） nm3, Z = 4. The monolcear lead cation is five-coordinated （ PbO3 N2 ） , showing distorted tetragonal pyramid geometry. Moreover, relying on N-H…O weak interactions, it forms three-dimensional supramolecular structure. CCDC ：983583 .
