Abstract
The title compound, [Sn(CH(3))(2)(C(16)H(15)NO(3))], 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 P3(2). The racemate crystallizes in the space group P1 with R and S enantiomers in the crystal lattice; these form dimers about a crystallographic inversion centre.
摘要
标题化合物[Sn(CH₃)₂(C₁₆H₁₅NO₃)]从一批反应产物中结晶出来，具有高对映体过量，包含纯对映体和外消旋体。S对映体在手性空间群P3₂中结晶。外消旋体在空间群P1中结晶，晶格中含有R和S对映体；它们围绕一个晶体学反演中心形成二聚体。
