ABSTRACT
The title compound 4-(8-chloro-[1,2,4]triazolo[4,3-α]pyridin-3-yl)phenol was structurally characterized by X-ray crystal structural analysis. The crystals are triclinic, space group P-1 with a = 7.307(3), b = 11.792(4), c = 12.474(5) Å, α = 83.850(10), β = 87.148(13), γ = 77.691(11)°, V = 1043.6(6) Å3, Z = 2, F(000) = 504, Dc = 1.564 g/cm3, μ = 0.350 mm−1, the final R = 0.0433 and wR = 0.1232. A total of 10,746 reflections were collected, of which 4920 were independent (Rint = 0.0357). In the crystal packing diagram, intermolecular O-H…Cl and C-H…O hydrogen bonds stabilize the solid state of the title compound.
