合成了三元混配配合物[Cu(L-Ile)(Phen)(H_2O)(ClO_4)](L-Ile=L=异亮氨酸,phen=1,10-邻菲咯啉),通过红外光谱、紫外-可见光谱、摩尔电导率、X射线单晶结构分析,对配合物进行了表征。该晶体属单斜晶系,P2_1空间群,晶胞参数:a=1.1704(5)nm,b=0.8090(5)nm,c=2.1822(5)nm,β=98.061(5)°,Z=2,D_x=1.60Mg·m~(-3),R_1=0.0462,wR_2=0.1225。每个配合物分子中Cu(Ⅱ)离子与一个L-Ile(N,O)配体、一个Phen(N,N)配体、一个H_2O(O)配体及一个Cl_O~-(O)形成六配位的畸变八面体构型。本文还用电位滴定法测定了配合物的稳定常数,结果表明,配合物具有高的稳定性。
The ternary complex [Cu (L-Ile) (Phen) (H_2O) (ClO_4)] (L-Ile = L = isoleucine and phen = IR, UV-Vis, molar conductivity, X-ray single crystal structure analysis, the complexes were characterized. The crystal belongs to the monoclinic system with a P2_1 space group with unit cell parameters of a = 1.1704 (5) nm, b = 0.8090 (5) nm, c = 2.1822 (5) nm and β = 98.061 2, D_x = 1.60 Mg · m -3, R_1 = 0.0462, wR_2 = 0.1225. The Cu (Ⅱ) ions and one L-Ile (N, O) ligand, one Phen (N, N) ligand, one H_2O (O) ligand and one Cl_O ~ - Six coordination distortion octahedral configuration. The stability constant of the complex was also determined by potentiometric titration. The results show that the complex has high stability.
