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.

Refinement top

All H-atom positional parameters were calculated geometrically and fixed with Uiso(H) = 1.2Ueq(parent atom).

Structure description top

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).
