Résumé
The coordination chemistry of 6-chloro-2-(quinolin-2-yl)-2,4-dihydro-1<i>H</i>-benzo[<i>d</i>][1,3]oxazine (<b>L</b>H<sub>2</sub>) towards zinc and mercury has been explored. The ligand exhibits high versatility and provides different environments to the metal centre as a function of its diverse coordination modes. In one of the isolated and characterized complexes, [Zn(<b>L</b><sub>OH</sub>)Cl<sub>2</sub>], the zinc centre is found pentacoordinated with the ligand present in an iminic “open” structure. The oxidized form, which contains the 4<i>H</i>-benzo[<i>d</i>][1,3]oxazine part (<b>L</b>), is also encountered in [Zn(<b>L</b>)Cl<sub>2</sub>], whereas the crystal structure of the trinuclear compound [Hg<sub>3</sub>(<b>L</b>H<sub>2</sub>)<sub>2</sub>Cl<sub>6</sub>] shows the ligand <b>L</b>H<sub>2</sub> in its original arrangement.
