摘要：

The reaction between Hg(CIO4)2and 5, 5-Dimethylimidazolidine-2-thione-4-one (L) has been investigated in water, diethylether and perchloric acid solutions. In water, three different complexes, HgL(C1O4)2.nH2O, HgL'C1O4and HgL'2(L' = deprotonated L) have been obtained; in diethylether HgLn(C1O4)2 (n = 1, 3–5) was prepared, whereas in perchloric acid solutions, besides the HgL2(CIO4)2 complex, a mercury(I) complex of formula HgL2C1O4 was obtained at high acid concentration. The mercury(I) complex can also be obtained at a lower acid concentration using a L:Hg(C1O4)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. © 1990, Taylor & Francis Group, LLC.
