GOLD(I) COMPLEXES OF ORGANIC NITROGEN-COMPOUNDS - SYNTHESIS AND STRUCTURES OF (PHTHALIMIDO)(TRIPHENYLPHOSPHINE)GOLD(I) IN CRYSTALS C6H4(CO)(2)N(AUPPH(3)) AND C6H4(CO)(2)N(AUPPH(3))CENTER-DOT-CHCL(3)

[O(AuPPh(3))(3)](BF4-)-B-+ has been found to be a powerful aurating re agent for phthalimide, to give (phthalimido)(triphenylphosphine)gold(I ) (1) in high yield. Two different crystal systems, with or without CH Cl3 molecules in the unit cell, have been obtained. In both cases the monoaurated diacylamido complex C6H4(CO)(2)N(AuPPh(3)) (1) is present as a monomer with linear two-coordinate gold atoms. The N-Au(I) bond l engths (2.028(4), 2.040(4) Angstrom) are similar to those found in oth er monoaurated complexes of the type R(1)R(2)N(AuPPh(3)) with strongly electron-withdrawing organic substituents R(1), R(2).
