Abstract
The bis(β-ketoenolates)nickel(II) adducts of piperidine, piperazine, methylpiperazine, and morpholine are isolated in the solid state and investigated by magnetic measurements and electronic and i.r. spectra. Magnetic measurements and electronic spectra give evidence of trans-octahedral configuration while i.r. spectra show that the amines are coordinated to the nickel atom towards the nitrogen atom. The new band found in the range 385–300 cm−1 for all complexes can be assigned to Ni—N vibration. In the Ni(DBM)2•4B (B = methylpiperazine and morpholine) the two additional bases are not coordinated to the metal atom.Keywords
