Tetraphenylborate salts of nickel(II) complexes have been prepared where the nickel(II) is bound to the tridentate Schiff base adducts of unsymm.-N,N-dimethyl or -N,N-diethylethylenediamine and the β-dicarbonyl compound, CH3COCHRC(O)H, R = CH3CO or C2H5OCO or 2-acetyl-5,5-dimethyl-1,3-cyclohexanedione. The synthesis involves reacting the chloro or bromo derivatives of the tridentate nickel(II) complexes with
摘要制备了镍(II)配合物的四苯基硼酸盐,其中镍(II)与非对称的-N,N-二甲基或-N,N-二乙基乙二胺的三齿席夫碱加合物和β-二羰基化合物CH3COCHRC (O)H,R = CH 3 CO或C 2 H 5 OCO或2-乙酰基-5,5-二甲基-1,3-环己二酮。合成包括使三齿镍(II)配合物的氯或溴衍生物与四苯硼酸钠在二氯甲烷中反应。用非配位的四苯基硼酸根离子取代卤素配体会导致一些异常的配位键合。对于CH3COCHRC(O)H三齿配体,形成双核+1阳离子,其中两个三齿镍(II)基团通过桥连的羟基配体彼此结合。对于固态的2-乙酰基-5,5-二甲基-1,3-环己二酮,与镍(II)离子结合的三齿配体的游离羰基占据了第二个镍(II)离子的第四配位点。在丙酮溶液中,据信第四坐标位置被溶剂占据。
