摘要:
AbstractThe coordination chemistry of 6‐chloro‐2‐(quinolin‐2‐yl)‐2,4‐dihydro‐1H‐benzo[d][1,3]oxazine (LH2) 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(LOH)Cl2], 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)Cl2], whereas the crystal structure of the trinuclear compound [Hg3(LH2)2Cl6] shows the ligand LH2 in its original arrangement.
