摘要: 用CNDO/2方法计算N-氧化吡啶-2-甲醛缩1,3-丙二胺合铜离子[Cu(piotn)(H_2O)_2]~(2+)和N-氧化吡啶-2-甲醛缩乙二胺合铜离子[Cu(pioen)(H_2O)]~(2+)的电子结构。以原子净电荷的变化和配合物大π键的形成说明配合物形成后红外谱中~vN-o波数少减和~vC=N波数增加的原因。

Abstract: The electronic structures of [Cu(piotn) (H_2O)2]~(2+) and [Cu(pioen) (H_2O)_2]~(2+) ions,where piotn is N,N′-trimethylene bis(N-oxopicolinaldimine) and pioen is N, N′-ethylene bis(N-oxopicolinaldimine), have been calculated by CNDO/2 method.Using the change of atomic net charges and formation of dolocalized π bond, we explain the directions of wave number shifts of ν_(N-O) and ν_(C=N) in their infrared spectra after the complexes have been formed.
