Intramolecular N -> Sn Coordination in Tin(II) and Tin(IV) Compounds Based on Enantiopure Ephedrine Derivatives
The syntheses and molecular structures of the intramolecularly coordinated tin(II) compounds {CH2N(Me)CH(Me)CH-(Ph)O}(2)SnL (2, L = lone pair; 4, L = W(CO)(5); 5, L = Cr(CO)(5)) and of the related hydroxido-substituted tin(IV) compound [{CH2N(Me)CH(Me)CH(Ph)O}(2)Sn(OH)](2)O, 6a, are reported. Also reported ported are the molecular structures of the enantiopure N,N'-ethylenebis-(1R,2S)-ephedrine, {CH2N(Me)CH(Me)CH(Ph)OH}(2) (1), and its hydrobromide {CH2N(Me)CH(Me)CH(Ph)OH}(2)center dot HBr (1a).
