The asymmetric unit of the title cyclic thiourea derivative, C10H12N2S, comprises two molecules, each of which has a twist about the CH2—CH2 bond within the five-membered ring. The major difference between the independent molecules is manifested in the relative orientations of the five- and six-membered rings [dihedral angles between the least-squares planes = 28.03 (11) and 41.54 (11)°]. A network of C—Hπ interactions consolidates the three-dimensional crystal packing.
