The complex formation between cobalt(II) and thiourea studied in solvents as ethyl acetate (Etac), propanol (PrOH) and propylene carbonate (PC). The stability order with respect to the solvent was PC > Etac > PrOH. This behaviour was discussed in terms of solvents properties as DN, AN, DEC. The influence of the donicity (DN) was the prevailing effect. The species formed when water is added to the solvent were also considered: Co(H2O4S2+ 2 seems to be formed when solvent is PrOH or PC, while Co(H2O)6 2+ when solvent is Etac. Some possible interpretations are proposed considering the acceptor ability (AN) of the solvents.
