Crystal structure of ethyl 2-cyano-2-(1,3-dithian-2-ylidene)acetate

Abstract

The title compound, C9H11NO2S2, contains a 1,3-dithiane ring which has a twist-boat conformation. The dihedral angle between the mean planes of the ethyl acetate group and the dithiane ring is 17.56 (13)°. In the crystal, molecules stack in layers up the a-axis direction, however, there are no significant intermolecular interactions present.
