Enantiomerically pure and racemic dimethyl{N‐[(2‐oxidonaphthalen‐1‐yl‐κO)methylidene]valinato‐κ2N,O}tin(IV)

The title compound, Sn(CH₃)₂(C₁₆H₁₅NO₃)], crystallized from one reaction batch with high enantiomeric excess as both a pure enantiomer and a racemate. The S enantiomer crystallizes in the chiral space group P3₂. The racemate crystallizes in the space group P with R and S enantiomers in the crystal lattice; these form dimers about a crystallographic inversion centre.
