Reactions of thioether carboxylic acids with mercury(II). Formation and X-ray crystal structure of mercury(II) mercaptoacetate
摘要:
Reactions of Hg(II) salts with thioether carboxylic acids o-C6H4CH(SCH COOH)(2)](2) (1a) and PhCH(SCH2COOH)(2) (3) in water were found to lead to the decomposition of these ligands with the formation of mercury(II) mercaptoacetate Hg(SCH2COOH)(2) (2) and aldehydes o-C6H4(CHO)(2) and PhCHO, respectively. A similar reaction was observed between Hg(NO3)(2) and CH3(CH2)(2)CH(SCH)COOH)(2) (4). The X-ray structure of Hg(SCH2COOH)(2) (2) shows a linear-S-Hg-S-moiety. The mechanism of the formation of 2 in the reactions between Hg2+ and thioether carboxylic acids in water is discussed. (C) 2003 Elsevier B.V. All rights reserved.
