环烷酸镍的汽油或甲苯溶液呈亮绿色,根据自旋允许d-d跃迁,在光谱的红和兰区有三个吸收带,其峰值分别是403、680和1170nm,络合物具有八面体构型。在Ni-Al体系中,当Al/Ni摩尔比<0.53,只发生配位体的交换反应,Al/Ni≥0.53,体系中发生还原反应,Ni(II)→Ni(I)→Ni(O)。在Ni-B体系中,只发生配位体交换反应,生成的氟-硼-镍络合物具有和环烷酸镍相类似的d-d吸收带,络合物也具有八面体构型。以上结论与磁化率法的结果一致。
Nickel naphthenate in gasoline or toluene solution is bright green, allowing for dd transition according to spin, with three absorption bands in the red and blue regions of the spectrum, with peaks at 403, 680 and 1170 nm, respectively, with the octahedral configuration of the complex . In the Ni-Al system, Al / Ni molar ratio of only 0.53, only the exchange reaction of the ligand occurs, Al / Ni ≥ 0.53, the reduction reaction occurred in the system, Ni (II) → Ni ). In the Ni-B system, only the ligand exchange reaction occurs. The resulting fluorine-boron-nickel complex has a d-d absorption band similar to that of nickel naphthenate, and the complex also has an octahedral configuration. The above conclusion is consistent with the result of magnetic susceptibility.
