heal.abstract	The possible formation of complexes of Mo, Fe, Cr and Ni during the extraction with Versatic acid 6 from an acidic solution is studied. Metal ions were produced by the dissolution of ferrous scrap with aqueous HCl in the presence of chlorine. With Versatic 6, Mo, Cr and Ni probably form monomeric complexes containing solvating acid molecules and only one carboxylate group is covalently bound per metal atom; suggesting the presence of hydroxyl groups. Thus, the proposed formulae for these metals are: MoV(OH)(5) . (0-6) HV and CrV . (0-3) HV. In the case of Ni it was not possible to define any composition of the complexes due to the low extractability of the metal by the organic extractant. Iron(III) forms trimeric complexes. The number of solvating acid molecules may vary from 0 to 3 and the presence of hydroxyl groups is possible.	en
