The helicene, pyrido[3,2-f]quinolino[6,5-c]cinnoline 5-oxide, was prepared by treatment of 6-hydroxylaminoquinoline with xanthine oxidase or treatment of 6-nitroquinoline with glucose in 30% NaOH and the product characterized using NMR, high resolution mass spectrometry, and X-ray crystallography. The hydrogens on carbons 7 and 12 of the terminal aromatic rings are separated by 2.495 Å creating an angle of 25.0° between the planes of the two quinoline ring systems. In the crystal, water molecules serve to link the helicenes into a one dimensional chain structure forming a hydrogen bonded bridge between N2 of one molecule and N4 of another. The molecule (C18H10N4O•H2O) crystallized in the monoclinic P21/n space group. Unit cell parameters for pyrido[3,2-f]quinolino[6,5-c]cinnoline 5-oxide monohydrate: a = 7.0829(12), b = 18.559(3), c = 11.0985(19) Å, β = 107.736(2)°, and Z = 4.
