Title: Reactivity of Mercury(II) Perchlorate Towards 5,5 -Dimethylimidazolidine-2- Thione-4-One. Structure of Bis(5,5-Dimethylimidazolidine-2-Thione-4-One)Mercury(II) Perchlorate Triaquo
Abstract: Abstract The reaction between Hg(GO4)2 and 5,5-Dimethylimidazolidine-2-thione-4-one (L) has been investigated in water, diethylether and perchloric acid solutions. In water, three different complexes, HgL(ClO4)2·nH2O, HgL′ClO4 and HgL′2 (L′ = deprotonated L) have been obtained; in diethylether HgLn(C104)2 (n = 1, 3–5) was prepared, whereas in perchloric acid solutions, besides the HgL2(CIO4)2 complex, a mercury(I) complex of formula HgL2ClO4 was obtained at high acid concentration. The mercury(I) complex can also be obtained at a lower acid concentration using a L:Hg(ClO4)2 molar ratio higher than 2:1. The crystal structure of bis(5,5-dimethylimidazolidine-2-thione-4-one) mercury(II) perchlorate triaquo shows the existence of the [HgL2]2+ cation, in which the coordination around the mercury atom is almost linear.
