Réactivité du trioxyde de chlore avec des chlorures, des nitrates, des carbonates et des perchlorates hydratés. Synthèse et analyse structurale de complexes de Cd(II) et Hg(II): Cd(ClO4)2, Hg(ClO4)2, ClO2Cd(ClO4)3, NO2Cd(ClO4)3, (NO2)2Hg(ClO4)4 et HgClClO

To improve the synthesis of perchlorato complexes of Cd(II) and Hg(II), reactions of Cl2O6 with CdCl2, CdCO3, Cd(NO3)2•nH2O, HgCl2, Hg(ClO4)2•6H2O, and Hg(NO3)2•H2O were tried. The complexes Cd(ClO4)2, ClO2Cd(ClO4)3, NO2Cd(ClO4)3, HgClClO4, Hg(ClO4)2, and (NO2)2Hg(ClO4)4 were characterized. Among these complexes only HgClClO4 is ionic (HgCl+ is a polymeric chain); the others are perchlorato complexes. Cd(ClO4)2 is related to the layered complexes M(ClO4)2 (M = Co, Ni, Zn) in which ClO4 is a bridging tridentate. Hg(ClO4)2 is close to HgCl2 or Hg(SR)2 (SR: thiocarbamate); ClO4 is a monodentate and it interacts with neighbouring molecules. In the salts ClO2Cd(ClO4)3, NO2Cd(ClO4)3, and (NO2)2Hg(ClO4)4 the anions have polymeric arrangements; their structures are analogous to those of ACuCl3, NO2Co(ClO4)3, and (NO2)2Cu(ClO4)4, respectively.
