- 論文の詳細を見る
The reactions of bis(acetylacetonato)nickel(II) with restricted amounts of dry hydrogen bromide have been performed in appropriate mixtures of dichloromethane and petroleum ether at room temperature or lower in order to isolate the intermediary products, Ni<SUB>3</SUB>Br(acac)<SUB>5</SUB>, Ni<SUB>3</SUB>Br<SUB>2</SUB>(acac)<SUB>4</SUB>, and Ni<SUB>3</SUB>Br<SUB>4</SUB>(acac)<SUB>2</SUB>. The essentially octahedral trinuclear structure of Ni<SUB>3</SUB>Br(acac)<SUB>5</SUB> was established on the basis of elemental analysis, by molecular-weight and magnetic-moment determinations, and by studying the electronic and IR spectra. Ni<SUB>3</SUB>Br<SUB>2</SUB>(acac)<SUB>4</SUB> and Ni<SUB>3</SUB>Br<SUB>4</SUB>(acac)<SUB>2</SUB> were characterized less satisfactorily because of their lower solubilities. The reactions of these mixed complexes with pyridine have also been examined; a new complex NiBr(acac)(py)<SUB>3</SUB> was thus obtained in addition to the known compound, Ni(acac)<SUB>2</SUB>(py)<SUB>2</SUB>.
