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.
