The AuIII atom in the title compound, (C11H7N2O)[AuCl4]·C11H6N2O, is in a nearly square-planar environment defined by four Cl atoms. The protonated 9-oxo-4,5-diazafluoren-4-ium cation forms an N-H
N hydrogen bond with the neutral 4,5-diazafluoren-9-one molecule.
Chloroauric acid trihydrate (0.25 g, 0.73 mmol) dissolved in acetonitrile (5 ml) was mixed with 4,5-diazafluoren-9-one (Henderson et al., 1984) (0.13 g, 0.73 mmol) dissolved in methanol (5 ml). The yellow solution was set aside for the growth of crystals, which appeared after two weeks (yield 70%; m.p. 483 K).
C-bound H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95 Å and with Uiso(H) = 1.2Ueq(C). The N-bound H atom was located in a difference Fourier map and refined isotropically, with a distance restraint of N—H = 0.88 (1) Å. The crystal diffracted strongly owing to the extremely heavy metal atom; however, its presence introduced severe absorption problems that could not be corrected analytically as the crystal did not have regular faces. The final difference Fourier map had a highest peak at 1.00 Å and a deepest hole at 1.00 Å from Au1 atom.
