Salts [XanH+]2[MCl42-] (where XanH+=protonated form of xanthine and M=Zn(II), Cd(II) and Hg(II) have been synthesized and studied by IR,1H-NMR, TG and DSC. The metal is not coordinated to the ligand and forms a salt-like structure. The cationic proton is on N(7). Thermal decomposition of these salts occurs in two steps: (i) dehalogenation and (ii) decomposition. Dehalogenation enthalpies have been calculated from DSC curves.Zusammenfassung(XanH+)2(MCl42-)-Salze (worin XanH+ die protonisierte… CONTINUE READING
