On the stereochemistry of 7-[1(2-carbomethoxyanilino)-1-(pyridyl)-methyl]-quinolin-8-ol (CMAP-oxine)

C₂₃H₁₉N₃O₃, P1 , a = 11,683(3), b = 7.740(2), c = 14.445(3) Å, α = 131.02(8), β = 95.43(8), γ = 95.02(8)°, D_x = 1.328 Mg · m⁻³, V = 0.9614 · 10⁻²⁷ m³, Final R = 0.059 for 2905 symmetrically independent reflections (|F₀| ≧ 3σ(F₀)). The intensities were measured with an automatic diffractometer. There are two molecules in the unit cell. The substance is not tridentat in potentially coordination behaviour; coordination takes place (twodentat) on the oxine group.
