The reaction between the iminophosphorane ligand N-phenyl-1,1,1-triphenylphosphanimine (NPh=PPh3) and anhydrous manganese(II) halides allowed isolation of complexes with general formula [MnX2(NPh=PPh3)2] (X = Cl, Br, I). compounds showed luminescence in green region attributed to 4T1(4G)→6A1(6S) transition metal centre tetrahedral field, which was superimposed cases X Cl Br on weak ligand-centred fluorescence. emission excitation spectra were compared those free related zinc(II) bromo-complex. DFT calculations bromo-complex helped rationalise experimental data. protonation NPh=PPh3 led formation iminium cation [NHPh=PPh3]+, used as a building block for synthesis organic–inorganic hybrids [NHPh=PPh3]2[MnX4] crystal structure [NHPh=PPh3]2[MnBr4] determined by means X-ray diffraction. Green photoluminescence associated metal-centred also observed hybrids, higher quantum yields respect neutral complexes. In case I, from that tetraiodomanganate anion upon compound near–UV light.
