本研究用复分解法合成了第一过渡系部分金属元素(Mn(Ⅱ)Fe(Ⅱ)、Fe(Ⅲ)、Co(Ⅱ)、Co(Ⅲ)、Ni(Ⅱ)Cu(Ⅱ)和Zn(Ⅱ))的布洛芬配合物。用化学分析、热分析和红外吸收光谱分析确定了这些配合物的组成为Mn(Ⅱ)B_2·H_2O、Fe(Ⅱ)B_2·2H_2O、Fe(Ⅲ)B_3·2H_2O、CO(Ⅱ)B_4·HB·2H_2O、Co(Ⅲ)B_3·2H_2O、Ni(Ⅱ)B_2·2H_2O、Cu(Ⅱ)B_2·H_2O和Zn(Ⅱ)B_2·2H_2O。用热分析及显微测熔测定了上述配合物的熔点及分解温度。红外光谱分析表明,上述配合物中心离子与羧基氧结合的M-O键的性质除Fe(Ⅱ)有较明显的离子键特征外,其余则离子键和共价键兼而有之,Δν=ν_(反对称)(coo~-)-ν_(对称)(coo~-)与中心离子外层d电子关系呈规律性变化,d—电子层为半(全)充满时,Δν均为190cm~(-1),随d~6～d~(10)电子数增加,Δν有规律地增大。表明d—电子对M—O成键有直接影响。
In this study, some transition metal elements such as Mn (Ⅱ) Fe (Ⅱ), Fe (Ⅲ), Co (Ⅱ), Co (Ⅲ), Ni (Ⅱ) II)) ibuprofen complexes. The chemical compositions, thermal analyzes and IR spectra of these complexes were confirmed as follows: Mn (Ⅱ) B 2 · H 2 O, Fe (Ⅱ) B 2 · 2H 2 O, Fe (Ⅲ) B 3 · 2H 2 O, CO (Ⅱ) B 4 · HB · 2H 2 O, Co (Ⅲ) B 3 · 2H 2 O, Ni (Ⅱ) B 2 · 2H 2 O, Cu (Ⅱ) B 2 · H 2 O and Zn (Ⅱ) B 2 · 2H 2 O. The melting points and decomposition temperature of the above complexes were determined by thermal analysis and microscopic measurement. IR spectroscopy showed that in addition to the obvious ionic bond characteristic of Fe (Ⅱ), the ionic bond and the covalent bond of the above-mentioned MO bond between the center ion of the above complex and the carboxylate oxygen have both Δν = ν_ ( (Symmetrical) (coo ~ -) with the outer ion of the center ion d regularly, the Δν of the d-electron layer is 190cm ~ (- 1), with d ~ 6 ~ d ~ (10) electron number increases, Δν increases regularly. This shows that d-electrons have a direct effect on M-O bonding.
