Abstract: The title compound, C₁₇H₁₉N₃O₃S, crystallizes with two closely similar independent molecules related by a pseudotranslation of c/2. Each molecule consists of three approximately planar moieties centred on the N₂CS group and the two ring systems. The packing involves classical H bonds of the form N_amide-HS and N_hydrazine-HOC, together with various weak hydrogen bonds and N_hydrazine-H interactions. The overall packing is three-dimensional, but layer substructures parallel to the xz plane can be readily identified. Each molecule forms a topologically equivalent set of hydrogen-bond interactions.
