The visible light induced rearrangement of a manganese(III) complex of an unsymmetrical tetradentate Schiff's base ligand, 4-[2-(2-hydroxyphenylmethyleneamino)ethylamino]pent-3-en-2-one, to a manganese(III) complex of the symmetrical ligand salen

Abstract
Visible light irradiation of [{Mn(L)(H2O)}2](ClO4)2·4H2O, which contains the tetradentate unsymmetric Schiff's dianionic ligand 4-[2-(2-hydroxyphenylmethyleneamino)ethylamino]pent-3-en-2-one, results in the formation of the dimeric [{Mn(salen)(H2O)}2](ClO4)2·H2O, which contains the symmetrical dianionic Schiff's base ligand N,N′-bis(salicylidene)ethylenediaminato; the X-ray crystal structure of the latter complex is reported.
