Abstract

20 new sulfito-complexes of the type: Cation ·[Co(Diox.H)2(SO3)(amine)] · n H2O and Cation ·[Co(Diox.H)2(SO3)2] · H2O (Cation: Na+, NH4 + amine.H+, CoL6 3+; CrL6 3+; L = H2O, NH3, en, urea; Diox.H2 = dimethylglyoxime or alicyclic α-dioxime willi C5 . . . C8) were obtained and characterized by middle and far FTIR, - electronic - and mass spectra. The protolytic equilibria of [Co(Diox.H)2(SO3)2]3- and [Co(Diox.H)2(SO3)(amine)]- were studied by spectrophotometric and potentiometric measurements.
