PHOTOLYTIC AND THERMAL-REACTIONS OF MU-3-AS[WCP(CO)2]3 WITH FE(CO)5 AND FE2(CO)9 - X-RAY STRUCTURE ANALYSES OF THE CLUSTERS FEW2CP2(CO)7[MU-3-AS-WCP(CO)3], FE2WCP(CO)8H[MU-3-AS-WCP(CO)3], AND FE2WCP(CO)8H[MU-3-AS-FECP(CO)2]

Mu-3-As[WCp(CO)2]3 (1) (Cp = C5H5) reacts with Fe(CO)5 photolytically and thermically to yield FeW2Cp2(CO)7[mu-3-As - WCp(CO)3] (5) and Fe2WCp(CO)8H[mu-3-As - WCp(CO)3] (6), respectively. Thermal reaction of 1 with Fe2(CO)9 leads to the compound Fe2WCp(CO)8H[mu-3-As - FeCp(CO)2] (7) besides 5 and 6. The products have been characterized by spectroscopic methods and X-ray crystallography.
