Linear coordination of Hg(II) by cysteamine
نویسندگان
چکیده
Combination of the hydrochloride salt of cysteamine (1) with HgCl2 in water affords the unique compound, [Hg{S(CH2)2NH3}2](Cl)2 (2) in which the S Hg S angle is nearly linear. The ammonium portion of the molecule forms short hydrogen bonding contacts with the sulfur atoms. A related S···H bond is observed in the structure of the free ligand 1 indicating that such bonding does not require the presence of a metal. The compounds were characterized with spectroscopic (H NMR, IR) and physical techniques (Mp, CH-analysis) as well as X-ray diffractometry. © 2002 Elsevier Science Ltd. All rights reserved.

Colorimetric sensing strategy for mercury(II) and melamine utilizing cysteamine-modified gold nanoparticles.
A quantitative colorimetric sensing strategy utilizing cysteamine modified gold nanoparticles (CA-AuNPs) as reporters for Hg(2+) and melamine was demonstrated. Cysteamine is a cheap and commercially available aminothiol and is also the most important chelating ligand in coordination chemistry possessing the ability to coordinate to Hg(2+) and melamine. The terminal thiol group in cysteamine is ...

The combination of HgCl2 with the disulfide salt of 2-aminoethanethiol (cystamine dihydrogen dichloride) in water yields a two-dimensional chain {[HgCl4][(NH3CH2CH2S )2]}n (1). It consists of six-coordinate Hg in [HgCl4]n units with bridging and termainal Cl atoms. The disulfide groups, (NH3CH2CH2S )2 are held between the [HgCl4]n chain with weak S S interactions. The chlorides in the [HgCl4]n ...
