Abstract

Octahedral Mn(II) complex with NNO donor Schiff base ligand (HL) containing 8-aminoquinoline moiety with general formula, [Mn(L)2] (1) has been synthesized and characterized. The structural, electronic and photoluminescent properties have been studied. The X-ray structure of complex (1) shows distorted octahedral geometry around manganese(II). Cyclic voltammetry study of the complex shows quasi-reversible Mn(II)/Mn(III) oxidation and ligand reduction. The π(L)→π∗(L) (ILCT) based emission properties of the ligand HL and Mn(II) complex, 1 have been studied. The electronic structure and spectral properties are interpreted by DFT and TDDFT computations.
