A novel ligational mode of pyrimidine-2-thione. Molecular structure of dimethyl-(4-trifluromethyl-6-methylpyrimidine-2-thionate)thallium(III)
摘要:
The reaction between 4-trifluromethyl-6-methylpyrimidine-2-thione (4-CF3-6-CH(3)pymSH) and dimethylthallium(III) hydroxide in methanol yielded [Me2Tl(4-CF3-6-CH(3)pymS)](4); this compound exhibits a tetranuclear structure with thionate ligands acting as bridges between two metallic atoms. Vibrational and H-1, C-13 and Tl-205 NMR spectra of the complex are discussed and related to the structure. (C) 2003 Elsevier Science B.V. All rights reserved.
