Abstract

Manganese(ii) tetrahedral complexes having general formula [MnX2L2] (X = Cl, Br, I; L = 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine-2-oxide) were isolated and characterized. The structures of the chloro- and bromo-derivatives were ascertained by single-crystal X-ray diffraction. The three species are appreciably luminescent in the green region upon excitation with UV light. The luminescence lifetimes are strongly dependent upon the choice of the coordinated halide. The rigid 1,3-diazaphospholidine-2-oxide moiety improved the photoluminescence features with respect to comparable phenylphosphonic diamide Mn(ii) derivatives.
