Complex of Mn(II) Perchlorate with (2-Methylenepropane-1,3-diyl)bis(diphenylphosphine Oxide): Synthesis, Structure, and Double Luminescence

摘要

The previously unknown complex [MnL2(MeOH)(2)](ClO4)(2) was synthesized in the methanol-dichloromethane system by the reaction of Mn(ClO4)(2)center dot 6H(2)O with (2-methylenepropan-1,3-diyl)bis(diphenylphosphine oxide) (L). According to X-ray diffraction data, its Mn2+ ion has a distorted octahedral environment Mn@O-6 formed by two chelate ligands L and two coordinated methanol molecules. At 298 K, this complex exhibits low-intensity double luminescence, the low-energy component of which is attributed to Mn2+-centered phosphorescence, and the high-energy component - to intraligand fluorescence.
