摘要
四水顺丁烯二酸镍配合物晶体是由苹果酸和碳酸镍反应制得的。在这一体系中，加热时苹果酸转化为马来酸并与镍离子络合形成标题配合物。本文测定了该配合物的电子吸收光谱和光声光谱，并用配位场理论定量地解释了其光谱性质，得到了配合物的晶场参数及中心离子的轨道能级。理论结果与实验结果的互洽表明了配合物晶体结构与电子结构的一致。
The complex of Ni [OOC-C2 H2-COOH ] 2· 4H2O is synthesized from (± )malic acid and nickel carbonate. In this system, the (±)malic acid is transferred to iran malic acid as it was heated and then it coordinates with the Ni (Ⅱ) ion forming the title compound. Its electronic absorption spectrum and photoacoustic spectrum are recorded at room temperature in ultra violet-visible-near infrared region. And they are explained quantitatively with the 3d orbits radial scaling theory proposed by us. The crystal field parameters and the d-d transition energy levels are obtained. However the calculated values are in good agreement with the observed ones.
