Cobalt(II) and nickel(II) complexes with N-benzyl- and N-(p-nitrobenzyl)iminodiacetic acids. Structural and vibrational spectroscopic characterization and DFT study

Cobalt(II) and nickel(II) complexes with N-benzyliminodiacetic acid (BnidaH2) and N-(para-nitrobenzyl)iminodiacetic acid (p-NO2BnidaH2), namely [Co(Bnida)(H2O)3]·H2O (1a·H2O), [Co(p-NO2Bnida)(H2O)3]·½H2O (2a·½H2O) and [Ni(p-NO2Bnida)(H2O)3]·½H2O (2b·½H2O) were characterized by IR spectroscopy and studied by DFT. Crystal structures were determined by X-ray structural analysis.81
