In the title compound, C17H21N3OS [common nomenclature: (R)-camphor 4-phenylthiosemicarbazone], the N—N—C—(S)—N fragment deviates slightly from planarity, with a maximum deviation of 0.0259 (12) Å for the hydrazinic N atom, and makes an angle of 29.55 (0)° with the aromatic ring. The molecular structure is stabilized by an intramolecular N—H...O hydrogen bond and a short N—H...N interaction with graph-set motifs S(6) and S(5), respectively. In the crystal, the centrosymmetric arrangement of the molecules resembles a herringbone packing motif along [001]. As a result of the steric effects of the camphor entity, an apolar organic periphery and the intramolecular nature of the hydrogen bonds, neither strong nor relevant intermolecular interactions are observed.
