Ethyl 6-(4-cyclo­propyl-1H-1,2,3-triazol-1-yl)pyridine-3-carboxyl­ate

In the title compound, C₁₃H₁₄N₄O₂, which has approximate mirror symmetry, the dihedral angles between the triazole ring and the cyclo­propane and pyridine rings are 87.1 (2) and 7.60 (9)°, respectively. In the crystal, inversion dimers linked by pairs of both C—H...N and C—H...O inter­actions generate R₂²(6) and R₂²(18) loops, respectively. Further C—H...N inter­actions form R₂²(10) loops and link the dimers into [110] chains.

Crystal structure of 4-(3-carb­oxy­pro­pan­amido)-2-hy­droxy­benzoic acid mono­hydrate

In the title hydrate, C₁₁H₁₁NO₆·H₂O, the organic mol­ecule is approximately planar (r.m.s. deviation for the non-H atoms = 0.129 Å) and an intra­molecular O—H...O hydrogen bond closes an S(6) ring. In the crystal, the benzoic acid group participates in an O—H...O hydrogen bond to the water mol­ecule and accepts a similar bond from another water mol­ecule. The other –CO₂H group forms a carb­oxy­lic acid inversion dimer, thereby forming an R₂²(8) loop. These bonds, along with N—H...O and C—H...O inter­actions, generate a three-dimensional network.
