摘要
N-对甲苯磺酰-α-丙氨酸(Ts-α-Hala),邻菲咯啉(phen)与金属氯化物在pH=3-4的水和有机溶剂中反应,合成了2个新颖的单核配合物[Cu(phen)(Ts-α-ala)2(H2O)](1)和[Mn(phen)(Ts-α-ala)(HCOO)(H2O)2](2)。X-射线单晶衍射分析表明,配合物1为三斜晶系,P1空间群,晶胞参数:a=1.1746(2)nm,b=1.1828(2)nm,c=1.4936(3)nm,α=70.22(3)°,β=88.26(2)°,γ=62.14(3)°,V=1.7060(8)nm3,Z=2,F(000)=774,R1=0.0553,wR2=0.1189;中心铜离子的配位多面体为畸变的四角锥体,配合物中存在分子间氢键,将配合物扩展为一维无限超分子链。配合物2为单斜晶系,P21/c空间群,晶胞参数:a=2.3944(2)nm,b=0.99292(11)nm,c=1.08029(11)nm,β=92.750(2)°,V=2.5654(4)nm3,Z=4,F(000)=1152,R1=0.0569,wR2=0.1105;有6个原子与中心锰离子配位形成畸变的八面体配位环境,配合物中存在丰富的氢键,将配合物扩展为二维层状超分子结构。
Two novel mononuclear complexes [Cu(phen)(Ts-α-ala)2(H2O)] (1) and [Mn(phen)(Ts-α-ala)(HCOO)(H2O)2] (2) were isolated from the mixed solvent reaction of N-p-Tolylsulfonyl-α-Alanine (Ts-α-Hala), 1,10-phenanthroline (phen) and CuCl2·2H2O (or MnCl2·4H2O), and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction analysis. Complex 1 is triclinic system, space group P1^- with the cell parameters: a=1.174 6(2) nm, b= 1.182 8(2) nm, c=1.493 6(3) nm, α=70.22(3)°, β=88.26(2)°, γ=62.14(3)°, V=1.706 0(8) nm3, Z=2, F(000)=774, R1= 0.055 3, wR2=0.118 9; The coordination polyhedron of copper ion is distorted square pyramidal. The intermolecular hydrogen bonds results in the structure of one-dimensional supramolecular chain of the complex. The complex 2 is monoclinic system, space group P21/c with the cell parameters: a=2.394 4(2) nm, b=0.992 92(11) nm, c=1.080 29(11) nm, β=92.750(2)°, V=2.565 4(4) nm^3, Z=4, F(000)=1 152, R1=0.056 9, wR2=0.110 5. The manganese ion is in a geometry of distorted octahedral built by six coordination atoms. There are a lot of hydrogen bonds in the complexe, forming a two-dimensional layered supramolecular structure.
