The title compound, C~11~H~12~Cl~2~N~2~OS, adopts a __trans__–__cis__ configuration of the isobutyryl and 2,5-dichlorophenyl groups with respect to the thiono S atom, across the thiourea C—N bonds. The crystal structure is stabilized by intermolecular N—H...S hydrogen bonding, forming dimers paralle
