Crystal structure of (S)-2-(2-oxopyrrolidin-1-yl)butanoic acid, C8H13NO3

C8H13NO3 ,m onoclinic, P21 (no. 4), a =6 .285(3) A, b =8 .010(4) A, c =9 .190(5) A, * =1 08.411(7)°, V =4 39.0 A 3 , Z =2 , Rgt(F) =0 .046, wRref(F 2 ) =0 .132, T =2 93 K. Source of material (S)- 2-(2-oxopyrrolidin-1-yl)butanoic acid of analytical purity grade was obtained commercially. Crystals of the title compound were acquired after 0.171 g( 0.001 mol) (S)-2-(2-oxopyrrolidin1-yl)butanoic acid recrystallized from 25 ml ethanol by slow of solvent evaporation in air. Experimental details All Ha toms were located at calculated positions and refined as riding on their parent atoms with the bond length fixed to 0.97 A (methylene), 0.96 A (methyl) and 0.82 A (hydroxyl) and with Uiso(H) being 1.2 Ueq(C) with the exception of Uiso(H) being 1.5.Ueq(O and Cf or methyl group). The Flack parameter value is x =0 .9(17).
