Gold(I) Complexes of Organic Nitrogen Compounds: Synthesis and Structures of (Phthalimido)(triphenylphosphine)gold(I) in Crystals C₆H₄(CO)₂ N(AuPPh₃) and C₆H₄(CO)₂N (AuPPh₃) · CHCI₃

[O(AuPPh₃)₃]⁺BF₄⁻ has been found to be a powerful aurating reagent for phthalimide, to give (phthalimido)(triphenylphosphine)gold(I) (1) in high yield. Two different crystal systems, with or without CHC1₃ molecules in the unit cell, have been obtained. In both cases the monoaurated diacylamido complex C₆H₄(CO)₂N(AuPPh₃) (1) is present as a monomer with linear two-coordinate gold atoms. The N – Au(I) bond lengths (2.028(4), 2.040(4) Å) are similar to those found in other monoaurated complexes of the type R¹R²N(AuPPh₃) with strongly electron-withdrawing organic substituents R¹, R². Crystal data: 1, monoclinic, P2₁/c, a = 9.948(1), b = 15.712(1), c = 14.651(1) Å, β = 103.40(1)°, V = 2227.7 ų, Z = 4; 1 · CHC1₃, orthorhombic, P2₁2₁2₁, a = 8.889(1), b = 10.349(1), c = 29.198(2) Å, V = 2686.0 ų, Z = 4.
