    Description / Table of Contents: Inorganic Cyclopentane Variants: Organometal-Arsenic Five-Membered Rings with Fe—Co—As—Fe—As and Mn—As—As—Mn—As BackbonesBy unusual reactions the polynuclear complexes Fe2CoCp3(CO)3(AsMe2)2 (1) and Mn2(CO)7Hal-(AsMe2)3 (2, Hal=Cl, Br) were formed in moderate to good yields. Both were identified crystallo-graphically as inorganic five-membered ring systems. 1 has a Fe—Co—As—Fe—As-, 2 has a Mn—As—As—Mn—As backbone. The geometry of 1 resembles the envelope conformation, that of 2 resembles the half-chair conformation of cyclopentane.
    Notes: Durch ungewöhnliche Reaktionen entstanden in mäßigen bis guten Ausbeuten die Mehrkernkomplexe Fe2CoCp3(CO)3(AsMe2)2 (1) und Mn2(CO)7Hal(AsMe2)3 (2, Hal=Cl, Br). Beide wurden kristallographisch als anorganische Fünfring-Systeme identifiziert. 1 hat ein Fe—Co—As—Fe—As-, 2 ein Mn—As—As—Mn—As-Gerüst. Die Geometrie von 1 ähnelt der „Briefumschlag“-Konformation, die von 2 der „Halbsessel“-Konformation des Cyclopentans.
