X-ray powder diffraction investigations of phenol derivatives

摘要

The X-ray powder diffraction patterns of three phenol derivatives-2-chlorophenol, 2,6-dichloro-4-nitrophenol, and 2,6-dichloro-phenoloindophenol tetrahydrate—were collected and the lattice parameters of these compounds were determined. The measurement for 2-chlorophenol was carried out at 250 K in a low-temperature chamber; this compound crystallizes in hexagonal system with a = 1.59602(8) nm, c = 0.59761(7) nm, space group P6 or P6_3/m. Investigated at room temperature, 2,6-dichloro-4-nitrophenol and 2,6-dichloro-phenoloindophenol tetrahydrate crystallize in the triclinic system with the unit cell parameters refined to a = 0.8169(2) nm, b = 1.6637(6) nm, c = 0.7440( 1) nm, α = 96.6(3)°, β =116.19(2)°, γ =78.68°, and space group P-1(2), and a = 0.7792(3) nm, b= 1.2795(4) nm, c = 0.7256(3) nm, α =91.17(5)°, β=96.93(4)°, γ = 85.41(3)°, and space group P-1(2), respectively.
