[Au{(AP,Rp-TPP4}]PF6: [NBu4][AuIJ (0.11 g, 0.14 mmol) was added to a solution of (RP,Rr)-TPPt (0.11 g, 0.14 mmol) in ethanol (20 cm') and thé mixture heated briefly on a steam bath. The volume of the solution was reduced by fa. 50% to give [Au{(#P,/?P)-TPP4}]I (0.14 g, 97%). The iodide salt was redissolved in acetone (20 cm5) and a solution of NH4PF6 (0.11 g, 0.880 mmol) in water (10 cm3) was added. The volume of the solution was reduced to ca. 10 cmto give a white solid that was subsequently recrystallised from acetonitrile by the addition of diethyl ether (0.11 g, 93%). mp 288 "C.
