Popis:	Reaction of (η5-C5Me5)(CO)2FeAs(SiMe3)2 (1) with equimolar amounts of (bis(trimethylsilyl)methylene]chlorophosphane afforded the 1-metallo-1-arsa-2-phosphapropene (η5-C5-Me5)(CO)2FeAs(SiMe3)P=C(SiMe3)2 (2) in addition to a few crystals of dimetallophosphaarsirane (η5-C5Me5)(CO)2Fe- AsC(SiMe3)2PFe(CO)2(η5-C5Me5) (3). Treatment of 2 with an excess of [(Z)-cyclooctene]Cr(CO)5 and subsequent chromatography furnished the phosphaarsirane-[Cr(CO)5] adduct (η5-C5Me5)(CO)2Fe-ηAsC(SiMe3)2PH[Cr(CO)5] (5). The molecular structures of 3 and 5 were established by single-crystal X-ray structure analyses.
