Pseudohalogeno Metal Compounds. LXXV. 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-tosyldicyanmethanide, 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)5 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.
Notes:
Die Pseudohalogenide (X-) Nitrosodicyanmethanid, o-Tsyldicyanmethanid, o-Tosylcyanamid und Diphenylthiophosphinylcyanamid setzen sich mit den „Metallorganischen Lewis-Säuren“ (OC)5Re+(als (OC)5ReFBF3) und Ph3PAu+ (als ph3PAuNO3) zu den nautralen Titel-Komplexen (OC)5Re - X bzw. Ph3PAu—X um. Nach der Röntgenstrukturanalyse sind Nitrosodicyanmethanid über das Nitroso-N-Atom an das Re(CO)5-Fragment, o-Tosyl-dicyanmethanid und o-Tosyl-cyanamid über ein Cyanid-N-Atom an die Ph3PAu-bzw. (CO)5Re-Gruppe gebunden. Diphenylthiophosphinylcyanamid ist dagegen über das Schwefel-Atom an das Gold-Atom koordiniert. Die spektroskopischen Daten (IR, NMR) von 1-6 werden beschrieben.
