    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.

    Description / Table of Contents: A Complex with Arsenic and Carbamoyl Bridge: Synthesis and Structure of Fe2(CO)6[μ—As(CH3)2][μ-OCN(CH3)2]Fe2(CO)9 reacts with (CH3)2As—N(CH3)2 in the presence of HN(CH3)2 to yield the title complex 4 which was characterized analytically and crystallographically. It contains a new five-membered ring system with two iron atoms, a dimethylarsenic and a dimethylcarbamoyl bridge as well as a metal-metal bond.
    Notes: Die Umsetzung von Fe2(CO)9 mit (CH3)2As—N(CH3)2 in Gegenwart von HN(CH3)2 liefert den Titel-Komplex 4, der analytisch und kristallographisch charakterisiert wurde. Er enthält ein neues fünfgliedriges Ringsystem mit zwei Eisenatomen, einer Dimethylarsen- und einer Dimethylcarbamoyl-Brücke sowie einer Metall-Metall-Bindung.
