2,5-二羟基-1,4-苯醌阴离子桥联配合物的合成与表征

Synthesis and characterization of complexes bridged by dianion of 2,5-dihydroxy-1,4-benzoquinone

在水和乙醇混合溶剂中 ,用 2 ,5-二羟基 - 1,4 -苯醌阴离子 ( DHBQ)为桥配体 ,首次合成了 Mn( )、Cu( )的桥联配合物 ,通过元素分析、差热 -热重分析及红外光谱研究 ,可以确定两种配合物都应具有链状结构 ,组成分别为 [Mn(μ- DHBQ) ( H2 O) 2 ]n 和 [Cu(μ- DHBQ) H2 O]n.

Two novel one\|dimension linear Mn(Ⅱ)、Cu(Ⅱ) complexes bridged by the dianion of 2,5\|dihydroxy\|1,4\|benzoquinone have been synthesized in water and ethanol. They were characterized by elemental analysis, IR spectra, UV spectra and DTA\|TG thermal analysis. The composition of those complexes are \[Mn(μ\|DHBQ)(H\-2O)\-2\]\-\%n\%、\[Cu(μ\|DHBQ)H\-2O\]\-\%n\% and coordination geometries are octahedral and square pyramidal, respectively.
