2,5-Dimethyl-3-(3-methylthiophen-2-yl)-perhydropyrrolo[3,4-d]isoxazole-4,6-dione

Abstract

The crystal structure of the title compound, C12H14N2O3S, exhibits intramolecular C-H center dot center dot center dot S and intermolecular C-H center dot center dot center dot S, C-H center dot center dot center dot O hydrogen bonds, C-S center dot center dot center dot N [S center dot center dot center dot N = 2.980 ( 2) angstrom, C-S center dot center dot center dot N = 145.78 (17)degrees]and C-H center dot center dot center dot pi interactions; these interactions generate two C( 5) chains and S( 4), S( 6) and R-4(4)( 28) ring motifs. The isoxazole ring has an envelope conformation; the N atom, which is the flap atom, is displaced by 0.261 ( 2) angstrom from the plane defined by the remaining four atoms. The dihedral angle between the succinimide and thiophene rings is 46.8 ( 2)degrees.
