title: [1,3-Bis(4-nitrophenyl)triazenido](triphenylphosphine)gold(I).
abstract: In the title complex, [Au(C(12)H(8)N(5)O(4))(C(18)H(15)P)], the coordination geometry about the Au(I) ion is linear, with one deprotonated 1,3-bis(4-nitrophenyl)triazenide ion, [O(2)NC(6)H(4)N=N-NC(6)H(4)NO(2)](-), acting as a monodentate ligand (two-electron donor), and one neutral triphenylphosphine molecule completing the metal coordination. The triazenide ligand is almost planar (r.m.s. deviation = 0.0767 A), with the largest interplanar angle being 11.6 (7) degrees between the phenyl ring of one of the terminal 4-nitrophenyl substituents and the plane defined by the N=N-N triad. The Au-N and Au-P distances are 2.108 (5) and 2.2524 (13) A, respectively. Pairs of molecules generated by centrosymmetry are associated into a supramolecular array via intermolecular C-H...O interactions, and N...C and N...O pi-pi interactions.
