In each of 2‐ethylsulfanyl‐7‐methyl‐4‐(4‐methylphenyl)pyrazolo[1,5‐ a ][1,3,5]triazine, C 15 H 16 N 4 S, (I), and 2‐ethylsulfanyl‐7‐methyl‐4‐(4‐nitrophenyl)pyrazolo[1,5‐ a ][1,3,5]triazine, C 14 H 13 N 5 O 2 S, (II), there is significant bond fixation in the heterocyclic component. While there are no direction‐specific intermolecular interactions in the structure of (I), the molecules of (II) are linked by a combination of C—H⋯O and C—H⋯S hydrogen bonds into sheets containing four types of ring, all centrosymmetric.
