Neutral tribromo(2-phenyl-1,8-naphthyridine)gold(III), AuBr3(N-N), was prepd. by reaction of KAuBr4 with the ligand in CHCl3/C2H5OH and was characterized by 1H NMR spectroscopy and x-ray diffraction. The mol. and crystal structure of AuBr3(N-N)·0.5 THF (triclinic, P1̅, a 11.314(2), b 12.350(3), c 14.628(3) \AA, a 107.96(3), b 98.86(3), g 107.29(3)°, Z = 4, 173 K) shows coordination of the N8 nitrogen atom situated in the unsubstituted pyridine ring to the planar four-coordinate AuIII center. Whereas the AuBr3N best planes and the coordinated naphthyridine rings are not far from orthogonal (w $\sim$ 105°), the Ph substituents were found in the crystal with a $\sim$ 22° dihedral angle relative to the naphthyridine plane. Intermol. Au···Br distances close to the sum of the van der Waals radii indicate very weak interactions to form a quasi-dimeric arrangement in the crystal. [on SciFinder(R)]
