摘要：

Reaction fo HgSO4 with one molar equivalent of L{L = [18[aneN2S4(1,4,10,13-tetrathia-7,16-diazacyclooctadecane)} or Me2]18[an eN2S4 (7,16-dimethyl-1,4,10,13-tetrathia-7,16-diazacyclooctadecane)} in refluxing MeOH-H2O for 15 min affords a colourless solution containing the complex cation [Hg(L)}2+. Addition of excess Pf6- counterion gives the complex [Hg([18]aneN2S4)](PF6)2 . 4/3H2O as a cream coloured solid. A single crystal X-ray structure determination shows mercury(II) bound to a severely distorted octahedral arrangement of the six macrocyclic donor atoms, Hg-S = 2.655(5), 2.735(4), 2.751(4), 2.639(5) angstrom, Hg-n = 2.437(11), 2.472(17) angstrom. The cation is in a rac configuration with the two SCH2CH2NCH2S linkages bound meridionally to the metal centre.
