| Abstract: | The reaction of dimethylthallium(III) hydroxide with picolinic acid (Hpic), 3-hydroxypicolinic acid (H23hpic) and 6-hydroxypicolinic acid (H26hpic) in an aqueous/methanol mixture afforded the complexes TlMe2(pic)] (1), TlMe2(H3hpic)] (2) and TlMe2(H6hpic)] (3), respectively. Complex 3′, NaTlMe2(6hpic)2]n, was obtained as a minor product from a methanolic solution of 3. Compounds 1–3 were characterized by IR and Raman spectroscopy and, in the cases of 1, 2 and 3′, by single-crystal X-ray diffraction. Complex 3′ is the first example of an H6hpic− heterobimetallic compound to be isolated. The 1H and 13C NMR spectra of 1 and 2 are also discussed. |
