采用溶剂热合成法合成了双核钆混配配合物[Gd(Ts-p-aba)_3(phen)]_2·2DMF·4.4H_2O(Ts-p-aba-=N-对甲苯磺酰对氨基苯甲酸根离子,phen=1,10-邻菲罗啉,DMF=N,N-二甲基甲酰胺),并利用红外光谱(FT-IR)、热重分析(TG-DSC)和X-射线单晶衍射等实验手段研究了配合物的组成、结构和性质。X-射线单晶衍射结果表明:该配合物晶体属三斜晶系,P1空间群,晶胞参数是:a=1.10505(12)nm,b=1.74570(18)nm,c=1.78163(19)nm,α=70.321(2)°,β=85.357(2)°,γ=82.600(2)°,V=3.2066(6)nm~3,M_r=2633.99,D_c=1.364 g/cm~3,Z=1,μ=1.197mm~(-1)。6个氧原子和2个氮原子在钆离子周围形成一个变形的反四方棱柱体配位环境。配合物存在着丰富的氢键,将配合物连接成二维层状超分子结构。
Synthesis of binuclear gadolinium gadolinium complex [Gd (Ts-p-aba) _3 (phen)] _2 · 2DMF · 4.4H_2O (Ts-p-aba- = N-p-toluenesulfonyl p-aminobenzene (Phen-1,10-phenanthroline, DMF = N, N-dimethylformamide) were synthesized and characterized by FT-IR, TG-DSC and X- Single crystal diffraction experimental methods to study the composition, structure and properties of the complex. The results of X-ray single crystal diffraction show that the complex crystal belongs to the triclinic system, the space group P1 has a unit cell size of a = 1.10505 (12) nm, b = 1.74570 (18) nm and c = 1.78163 (19) (2) °, γ = 82.600 (2) °, V = 3.2066 (6) nm ~ 3, M_r = 2633.99 and D_c = 1.364 g / cm ~ = 1, μ = 1.197mm ~ (-1). Six oxygen atoms and two nitrogen atoms form a distorted anti-tetragonal prism coordination environment around gadolinium ions. The complexes exist rich hydrogen bonds, the complexes into two-dimensional layered supramolecular structure.
