[1,2-Diphenyl-N,N'-bis(salicylidene)-(RR,SS)-1,2-ethanediyldiaminato]nitridomanganese(V)

H. Iwamoto, M. Tsuchimoto and S. Ohba

The title compound, [MnN(C₂₈H₂₂N₂O₂)], has a distorted square-pyramidal coordination with an Mn [triple bond]

N bond length of 1.516 (2) Å at the apical position. The five-membered chelate ring adopts a gauche conformation with the two phenyl groups in equatorial orientations.

Comment top

The crystal structure of [MnN{sal-(SS)-stien}]^.CH₃CN was reported by Chang et al. (1998). We report here the crystal structure of [MnN(sal-rac-stien)], (I).

Experimental top

The title compound, [MnN(sal-rac-stien)], was prepared under aerobic conditions by the reaction of the chloromanganese(III) complex [MnCl(sal-rac-stien)] with NH₄OH (15 equivalents) and NaOCl (6 equivalents). Crystals were grown from an acetonitorile solution.

Special details top

Refinement. Refinement using reflections with F² > 0.0 σ(F²). The weighted R-factor (wR), goodness of fit (S) and R-factor (gt) are based on F, with F set to zero for negative F. The threshold expression of F² > 2.0 σ(F²) is used only for calculating R-factor (gt).
