Ethyl 1-benzyl-5-{[(isopropyl-amino)(3-nitro-phen-oxy)methyl-idene]amino}-1H-1,2,3-triazole-4-carboxyl-ate.

In the title compound, C22H24N6O5, the triazole ring is essentially planar with a maximum deviation of 0.005 (2) Å and forms dihedral angles of 79.78 (11) and 86.22 (11)° with the phenyl and benzene rings, respectively. In the crystal, molecules are linked by intermolecular N—H⋯N, C—H⋯O and C—H⋯π interactions into a three-dimensional network.

3-Benzyl-6-butyl-5-propyl-3H-1,2,3-triazolo[4,5-d]pyrimidin-7(6H)-one

In the title compound, C18H23N5O2, the triazolopyrimidine ring system is essentially planar, with a maximum displacement of 0.032 (2) Å, and forms a dihedral angle of 87.59 (15)° with the phenyl ring. In the crystal, molecules are linked by intermolecular C—H⋯O hydrogen bonds and C—H⋯π interactions into chains parallel to the c axis.

Ethyl 2-(3,3-dibutyl­thio­ureido)-4,5,6,7-tetra­hydro­benzo[b]thio­phene-3-carboxyl­ate

In the title compound, C20H32N2O2S2, the cyclohexene ring is disordered over two half-boat conformations with occupancy factors of 0.71:0.29. One n-butyl chain is also disordered over two positions with occupancy factors of 0.83:0.17. The molecular conformation is stabilized by an intramolecular N—H⋯O hydrogen bond.
