The complexes are N-salicylidene-L-alanine dihydrated cobalt(Ⅱ) (CoSAAL (H2O)2), N-salicylidene-L-leucine monohydrated cobalt (Ⅱ) (CoSALL(H2O)) and N-salicylidene-L-phenylalanine dihydrated cobalt(Ⅱ) (CoSALPHENA(H2O)2). The solents employed are pyridine (Py) anddimethylformamide (DMF).展开更多

UV- VIS spectra indicate that the solutions of complexes in DMF can reversibly combine with dioxygen. Oxygenation ratio 2: 1(Cu: O2) was proved through manometric oxygen-uptake measurements.展开更多
