A mononuclear Ni(II) complex having an acireductone type ligand, and supported by the bnpapa (N,N-bis((6-neopentylamino-2-pyridyl)methyl)-N-((2-pyridyl)methyl)amine) ligand, [(bnpapa)Ni(PhC(O)C(OH)C(O)Ph)]ClO4 (14), has been prepared and characterized by elemental analysis, 1H NMR, FTIR, and UV−vis. To gain insight into the 1H NMR features of 14, the air stable analogue complexes [(bnpapa)Ni(CH3C(O)CHC(O)CH3)]ClO4
一种单核 Ni(II) 配合物,具有 acireductone 型配体,并由 bnpapa ( N , N -bis( (6- nepentylamino -2-pyridyl)methyl) -N -((2-pyridyl)methyl)amine) 配体支持, [(bnpapa)Ni(PhC(O)C(OH)C(O)Ph)]ClO 4 ( 14 ) 已制备并通过元素分析、1 H NMR、FTIR 和 UV-vis 进行表征。为了深入了解14的1 H NMR 特征,空气稳定的类似物复合物 [(bnpapa)Ni(CH 3 C(O)CHC(O)CH 3 )]ClO 4 ( 16 ) 和 [(bnpapa)Ni(ONHC (O)CH 3 )]ClO 4 ( 17) 制备并通过 X 射线晶体学、1 H NMR、FTIR、UV-vis、质谱和溶液电导率测量表征。化合物16和17是 CH 3 CN中
