摘要 合成了D-甘露糖肟的混价四核铜配合物,通过元素分析、红外光谱、热分析和X射线光电子能谱等技术对配合物进行了表征及结构分析。结果表明,配合物分子中包含2个Cu(Ⅱ)原子和2个Cu(Ⅰ)原子,其中1个Cu(Ⅱ)与2分子配体肟基的2个N原子和2个羟基O原子配位,另1个Cu(Ⅱ)与1分子配体上的1个羟基O原子和1个解离羟基O-配位,与另1分子配体的1个羟基O原子和肟基的1个N原子配位,每个Cu(Ⅰ)与2个糖肟骨架上的2个羟基O原子和1个OH-配位,4个铜离子通过3个去质子化的配体桥连成链。OH-的加入是配合物形成的关键。 We synthesized a complex formed between Dmannose oxime and copper cations with mixed valence. The title compound was characterized by means of elemental analysis, IR, thermal analysis and XPS, etc. The results indicate that the compound is a tetranuclear copper complex having two Cu （Ⅱ） and two Cu（ Ⅰ ） metal centers. One Cu（Ⅱ） atom is coordinated by two nitrogen atoms and two oxygen atoms from two ligands while the other Cu （Ⅱ） coordinates with one nitrogen atom and three oxygen atoms. Each Cu （Ⅰ ） atom bonds to three oxygen atoms and one hydroxyl ion. The four copper atoms are linked by three deprotonated D mannose oxime molecules to form a chain. The pH plays a decisive role in the formation of the comnlexA
