摘要： 由于发生歧化离解,Mo2O3(S2CNEt2)4的溶液不遵守Beer定律,我们测定了有关溶液的光吸收性质以及Mo2O3(S2CNEt2)4的歧化离解常数,于15℃时数值为2.2×10-4。

Abstract: The solution of Mo2O3(S2CNEt2)4 does not obey Beer's law because of disproportional dissociation in to MoO(S2CNEt2)3 and MoO2(S2CNEt2)2. The dissociation constant has been determined spectrophotometrically as 2.2×10-4 at 15℃.The solution of Mo2O8 (S2CNEt2)4 in CH2Cl2 can be oxidized by air to form MoO2(S2CNEt2)2.The solution of MoO(S2CNEt2)2 in CH2Cl2 reacts with oxygen in air to form Mo2O3 (S2CNEt2)4 at first and then to be oxidized further to form MoO2(S2CNEt2)2.
