The reaction between (triphenylphosphine)acetatogold(I) and concentrated sulphuric acid in methanol leads to (Ph3PAu)2SO4 (1) or [(Ph3PAu)3O]+ HSO4- , depending on the acid concentration. The crystal structure of the methanol solvate of (1) was determined [C2/c, a = 1348.3(2), b = 1451.0(2), c = 1853.8(3) pm, β = 99.90(2)°, Z = 4, R = 0.037 for 3138 unique observed reflections], 1 possesses crystallographic twofold symmetry, with Au -O 206.3, Au -P 221.6 pm. The corresponding selenate is isomorphous.
