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

C 23 H 19 N 3 O 3 , P 1 , 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 m 3 , Final R = 0.059 for 2905 symmetrically independent reflections (| F 0 | ≧ 3σ( F 0 )). 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.
