• The liquid-liquid partition of nickel(II) between hexane containing trioctylphosphine oxide or 4-methyl-2-pentanone and 1 mol dm<SUP>−3</SUP> Na(SCN, ClO<SUB>4</SUB>) solutions at 25 °C was measured. The absorption spectra of the organic and aqueous phases at equilibrium were also measured. From an analysis of these data, the extraction constant and absorption spectrum of each organic species were determined. By comparing the extraction and optical absorption of cobalt(II) complexes in the same systems with the above results for nickel(II), it was concluded that cobalt(II) thiocyanate complexes changed from octahedral to tetrahedral form upon extraction, but that nickel(II) thiocyanate complexes remained in octahedral form throughout.
