 Title    Clusteraufbau durch Photolyse von R3PAuN3  
 Abstract    , III [1] Synthese von [(Ph3PAu)5Fe(CO)3]PF6 und Ru3(CO)10(jM-AuPPh3)(/i-NCO) Cluster Synthesis by Photolysis of R3PA uN 3, III [1] Synthesis of [(Ph3PA u)5Fe(C O)3]PF6 and R u3(C O)10(«-A uPPh3)(w-NCO) Photolysis of a mixture of Ph3P A u N 3 with F e(C O)5, Fe2(C O)9 or Fe3(C O),2 in TH F yields [(Ph3P A u)5F e(C O)3]+ (1) which crystallizes with PF6" as counterion as air stable, yellow platelets in the space group P2,/c: a = 2230.0(7), b = 1655.0(6), c = 2462.7(8) pm, ß = 94.04(5)°, Z = 4. The cationic A u5Fe cluster forms a bicapped F eA u 3 tetrahedron with almost equal Fe — A u dis­ tances o f 259.0 to 265.1 pm to all five A u atoms. D ue to the local symmetry C3|, o f the F e(C O)3 group two v(CO) at 1880 and 1930 c m ' 1 are observed. C o-photolysis of R u3(C O),2 and Ph3P A uN 3 does not result in a cleavage of the R u3 cluster. Bridging ,w-AuPPh3 and /^-NCO groups substitute two CO ligands to form Ru3(C O)10 («-A uPP h3)(u-N C O) (2).
