Preparation of two series of the cobalt(III) complexes, Na[Co(CN)<SUB>2</SUB>(SB)] and [Co(acac)(SB)], was carried out. CN, acac and SB respectively refer to cyanide anion, acetylacetonate anion and the quadridentate Schiff base anion, <I>N</I>,<I>N</I>′-polymethylenedi(salicylideneamine), <I>N</I>,<I>N</I>′-polymethylenedi(α-methylsalicylideneamine) or <I>N</I>,<I>N</I>′-polymethylenedi(2-hydroxy-1-naphthylmethyleneamine). Efforts to obtain Na[Co(CN)<SUB>2</SUB>(SB)] only containing the last Schiff base were unsuccessful. It was concluded from their PMR spectra that, for the dicyano complexes, the structure changes from a <I>trans</I>-form to a <I>cis</I>-one <I>via</I> a distorted <I>trans</I>-form, whereas for the acetylacetonato complexes, it changes from a distorted <I>cis</I>-β-form to an undistorted one with an increase in the length of carbon chain in the bridged polymethylene group of the Schiff bases.
