N2  - Linear, two-coordinate compounds of molecular formula (PPh3) AuX have been characterized by solid-state and solution 31P n.m.r. spectroscopy, and single-crystal X-ray diffraction techniques. The solid state n.m.r. spectra reveal single, broad resonance lines for X = NO3 (chemical shift 19 ppm , ref. 85% H3PO4), CH3C02 (24 ppm), SCN (36ppm), CN (37 ppm ) and CH3 (47 ppm ) and doublets for X = Cl (27, 33 ppm ), Br (28, 36 ppm ) and I (34, 38 ppm ), the latter three spectra being recorded at 121.47 MHz and 161.96 MHz. Solution spectra show relatively sharp single resonances for each compound with 6 values generally slightly higher than in the solid state. Crystal data are reported for X = NO3, space gro )p P21/c, a 8 895(9), b 10.117(8), c 19.57(2) Å; &#946; 97.43(8)º, Au-P,O = 2.199(5), 2.02(1) Å. Crystals of compounds with X = Br, I and SCN are isomorphous with the AuCl compound, belonging to space group 212121. For X = Br, a 12.479(5), b 13.45(1), c 10.0!2(8) Å; Au-P, Br = 2.252(6), 2.407(2) Å. For X = I, a 12.529(8), b 13.870(5), c 10.188(4) Å; Au-P, I = 2.254(5), 2.556(2) Å. For X = SCN, a 12.257(5), b 13.776(8), c 10.754(6) Å; Au-P, S = 2.252(7), 2.304(7) Å.
