Adducts of long-chained alkylamines and diaminoalkanes with some β-diketonates of nickel(II) and cobalt(II)

Bis adducts of n -hexyl, n -octyl, n -undecyl and n -hexadecylamine with the trifluoroacetyl-acetonates of nickel(II) and cobalt(II) have been prepared. They are octahedral complexes similar to compounds previously reported. Mono adducts of hexamethylenediamine, 1,11-diaminoundecane and 1,12-diaminododecane with the acetylacetonates and trifluoroacetylacetonates of nickel(II) and cobalt(II) and with the dipivaloylmethanate of nickel(II) have been prepared. Spectral properties and molecular weights indicate a polymeric, pseudo-octahedral structure for these complexes.
