| 摘 要： | 用光谱法研究了NiL2 在 30℃时与乙胺、正丙胺、正丁胺和正戊胺在乙醇溶液中的加合反应。伯胺类氮碱 (B)与NiL2 生成 1∶1的五配位NiL2 ·B和 1∶2的六配位NiL2 ·B2 两种加合物。所有五配位NiL2 ·B和六配位NiL2 ·B2 加合物的吸收光谱分别由NiNS4和NiN2 S4发色基团所产生。实验测定了反应的平衡常数lgβn 及加合分子数n。lgβn 随胺类碱度 pKa值增加而增大 ,且可以经验公式来描述lgβ1 =- 9 6 9+1 15pKa ;lgβ2 =- 18 73+2 2 8pKa

| Abstract: | Reaction of Ni(C4H9O)2PS2]2 with ethylamine, n-propylamine, n-butylamine, and n-amylamine have been studied by spectrophotometry in ethanol at 30 degrees C. For nitrogen base(B), the adduct formation of NiL2.B and NiL2.B2 is established, and their additive equilibrium constants (lg beta n) and molecular number (n) have been discussed. All the NiL2.B and NiL2.B2 complexes exhibit virtually the same electronic spectra arising from the five-coordinate NiNS4 and six-coordinate NiN2S4 chromophore respectively. The constants (lg beta n) increase with basicity (pKa) of nitrogen base and can be described by experimental formulas: lg beta 1 = -9.69 +1.15 pKa; lg beta 2 = -18.73 +2.28 pKa. |
