本文研究了乙酰丙酮铂(II)、乙酰丙酮钯(II)的光电子能谱和核磁共振谱的特性,提出了乙酰丙酮与Pt(II)、Pd(II)的配位方式,认为除了形成M←L的σ配位键外,还形成了M→L的dxz(dyz)→π13反馈π键,从而解释了乙酰丙酮与Pt(II)、Pd(II)形成稳定配合物的原因。
In this paper, the photoelectron spectra and NMR spectra of platinum (II) acetylacetonate and palladium (II) acetylacetonate were studied. The coordination mechanism between acetylacetone and Pt (II) and Pd (II) L, the dxz (dyz) → π13 feedback π bond of M → L is also formed, which explains the reason why acetylacetone forms a stable complex with Pt (II) and Pd (II).
