Novel rhenium(V) complexes were isolated from reactions of [NBu(4)][ReOCl(4)] with the potentially pentadentate Schiff base PhP{C(6)H(4)-2-(HC=N(C(6)H(4)-2-OH))}(2), H(2)L(1), and the corresponding amine PhP{C(6)H(4)-2-(CH(2)-NH(C(6)H(4)-2-OH))}(2), H(4)L(2). While the Schiff base undergoes partial hydrolytic decomposition and a redox reaction, the amine remains intact and acts as a pentadentate ligand, which encapsulates the metal atom of the {Re(V)O}(3+) core or stabilizes a {Re(V)Cl}(4+) center by the formation of an imido-type ligand system.
新型铼（V）配合物是通过[NBu(4)][ReOCl(4)]与潜在的五齿席夫碱PhP{C(6)H(4)-2-(HC=N(C(6)H(4)-2-OH))}(2)，即H(2)L(1)，以及相应的胺PhP{C(6)H(4)-2-(CH(2)-NH(C(6)H(4)-2-OH))}(2)，即H(4)L(2)反应分离得到的。虽然席夫碱会发生部分水解分解和氧化还原反应，但胺保持完整并作为五齿配体，它通过形成亚氨基型配体体系包裹{Re(V)O}(3+)核的金属原子或稳定{Re(V)Cl}(4+)中心。
