“…The electrolysis of a solution of 1-hydroxypyridine-2(1H)-thione (HL10) and bipy with a cadmium anode, gave the mixed Cd(II) insoluble complex [Cd(L10) 2 (bipy)]·H 2 O [290]; from the remaining solution, crystals of [Cd(L10)(bipy) 2 ]ClO 4 useful for X-ray diffraction studies were obtained. The structure of this complex is discussed later (vide infra, Section 4).Gallium, indium and thallium anodes were successfully used for the electrolysis of acetonitrile solutions of HL10[44]. The corresponding Ga(III), In(III) and Tl(I) complexes were obtained after the electrolytic process.…”

Replacing oxygen by sulfur in a maltol molecule generates a family of new very interesting ligands: thiohydroxypyrones. In this work, theoretical calculations have been performed for all possible maltol derivatives created by consecutive substitutions of oxygen atoms by sulfur. The study is focused on molecular properties of thioligands, which are important for the formation of their metal complexes, and potentially useful in medicinal and environmental chemistry. Energetic, tautomeric, aromatic, and charge distribution data are reported and the results are compared with maltol properties. It is shown that, similar to maltol, the most stable tautomer for all thio derivatives, is the one with the keto-enol group. The protonation in cations occurs always on the heteroatom of the (thio)ketone group. The study has been carried out with the aid of some aromaticity indices, such as HOMA, NICS, and ASE. Aromaticity is studied in the heterocyclic pyran ring and in the XCCX part (where X -oxygen or sulfur). All calculations were performed at the B1LYP/6-311RRG(d,p) level of theory. We conclude that the aromaticity order determined previously for maltol (cation > neutral molecule > anion) is also preserved for thiohydroxopyrones. The results of the population analysis indicate that upon protonation, a large portion of additional positive charge delocalizes on the entire molecule, whereas upon deprotonation, negative charge accumulates mainly on the heteroatoms of the XCCX group.

The crystal structures of [Tl(tsac)] (1) and [Tl(tsac)-(ophen)] (2) (tsac ϭ anion of thiosaccharin; ophen ϭ 1,10 phenanthroline) have been determined at 116 K by single crystal X-ray diffractometry. Complex 1 crystallizes in the monoclinic space group P2 1 /a with Z ϭ 4 and complex 2 in the monoclinic space group C2/c with Z ϭ 8.In both complexes T I is coordinated to a thiosaccharinate anion through its sulphur and nitrogen atoms. A distorted eight fold coordination sphere around the cation in complex 1 is completed with two other longer Tl-S bonds and four Kristallographische und spektroskopische Charakterisierung von zwei neuen Thallium(I)-Thiosaccharinat-KomplexenInhaltsübersicht.
