PSEUDOHALOGENO METAL-COMPOUNDS .75. PENTACARBONYLRHENIUM AND TRIPHENYLPHOSPHINEGOLD COMPLEXES OF PSEUDOHALIDE ANIONS - (OC)5REX, PH3PAUX (X=ONC(CN)2, O-MEC6H4SO2C(CN)2, O-MEC6H4SO2NCN, PH2(S)PNCN)

The pseudohalides (X-) nitrosodicyanmethanide, o-tosyldicyammethanide, o-tosylcyanamide and diphenylthiophosphinylcyanamide react with the Organometallic Lewis Acids (OC)5Re' (as (OC)5ReFBF3) and Ph3PAu+ (as Ph3PAuNO3) to give the neutral title complexes (OC)5Re-X and Ph3PAu-X, respectively. X-ray diffraction shows that nitroso-dicyanmethanide is coordinated through the nitroso N-atom to the Re(CO), fragment. Cyanide-N-coordination is observed for the complexes with o-tosyldicyanmethanide and o-tosylcyanamide whereas diphenylthiophosphinylcyanamide is S-coordinated to the gold atom. Spectroscopic data (IR, NMR) of 1-6 are described.
