Abstract
The coordination chemistry of 6-chloro-2-(quinolin-2-yl)-2,4-dihydro-1H-benzo[d][1,3]oxazine (LH 2 ) 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(L OH )Cl 2 ], the zinc centre is found pentacoordinated with the ligand present in an iminic "open" structure. The oxidized form, which contains the 4H-benzo[d][1,3]oxazine part (L), is also encountered in [Zn(L)Cl 2 ], whereas the crystal structure of the trinuclear compound [Hg 3 (LH 2 ) 2 Cl 6 ] shows the ligand LH 2 in its original arrangement.
