The synthesis of alkylmanganese(III) complexes. Crystal structure of MnMe(2-Me₂NCH₂C₆H₄)₂

Treatment of bis(3-N,N-dimethylaminopropyl)manganese(II) with methyllithium and subsequently with silver tetrafluoroborate gives bis(3-N,N-dimethylaminopropyl)methylmanganese(III) (1). The related complex bis(2-N,N-dimethylaminomethylphenyl)methylmanganese(III) (2) was prepared similarly. The structure of 2 was established by single-crystal X-ray crystallography. The molecule is trigonal bipyramidal, with aryl ipso carbon atoms in the axial positions and the two nitrogen atoms plus the methyl carbon forming the equatorial plane.
