Abstract

In the title compound, C13H12Cl2O4S, both C=C double bonds adopt an E conformation. The S atom has a distorted tetra-hedral geometry with bond angles ranging from 103.03 (12) to 118.12 (13)°. The eth-oxy-carbonyl group is disordered over two sets of sites, with site-occupancy factors of 0.739 (11) and 0.261 (11). In the crystal, C-H⋯O inter-actions link the mol-ecules into chains mol-ecules running parallel to the a axis.
