合成了12个镧系高氯酸盐的高熔点双(正-辛基亚砜)乙烷(α-BOSE)络合物。元素分析、摩尔电导、红外光谱、热谱和电子光谱等研究证实,络合物组成为:Ln(ClO_4)_3(BOSE)_3·nH_2O(Ln=La、Sm、Gd、Ho、Tm、n=0;Ln=Ce、Pr、Nd、Eu、n=2)和Ln_2(ClO_4)_6(BOSE)_5·4H_2O(Ln=Dy、Er)以及Yb(ClO_4)_3(BOSE)_2·2H_2O。络合物中的BOSE均通过>S=O基团的氧原子与镧系离子结合。随镧系离子半径减小,络合物的配位数、共价参数和热稳定性等均有减小倾向。
Twelve high-melting-point bis (n-octyl sulfoxide) ethane (α-BOSE) complexes of lanthanum perchlorate were synthesized. The results of elemental analysis, molar conductance, infrared spectra, thermal and electron spectroscopy confirm that the complex consists of Ln (ClO_4) _3 (BOSE) _3 · nH_2O (Ln = La, Sm, Gd, Ho, Tm, Ln = Ce, Pr, Nd, Eu, n = 2) and Ln_2 (ClO_4) _6 (BOSE) _5 · 4H_2O (Ln = Dy, Er) and Yb (ClO_4) _3 (BOSE) _2 · 2H_2O. BOSE in the complex binds to the lanthanide ions through the oxygen atom of the> S = O group. As the radius of lanthanide ions decreases, the coordination number, covalent parameter and thermal stability of the complexes decrease.
