    Description / Table of Contents: Reactions of Dimethyl Sulfoxide with Molybdenum Tetrabromide and Molybdenum Dibromide Dinitrosyl. Crystal Structure of [MoBr2(NO)2(OSMe2)2]In the cold molybdenum tetrabromide reacts with an equivalent amount of dimethyl sulfoxide forming the solvate [MoBr4(OSMe2)2]; excess dimethyl sulfoxide yields [MoO2Br2(OSMe2)2] which is also obtained by other methods. Molybdenum dibromidedinitrosyl forms the solvate [MoBr2(NO)2(OSMe2)2] in the reaction with dimethyl sulfoxide. According to the i.r. spectra all complexes display O-coordination of the OSMe2 molecules. [MoBr2(NO)2(OSMe2)2] crystallizes monoclinic in the space group P21/c with four formula units per unit cell. The cell dimensions are a = 1236, b = 892, c = 1305 pm, β = 95.2°. 1662 independent observed reflexions were used for refinement; R = 3.8%. The molybdenum atoms are six-coordinated, the O atoms of the dimethyl sulfoxide molecules are in trans-position to the nitrosyl ligands, which form linear groups Mo—N—O.
    Notes: Molybdäntetrabromid reagiert mit der äquivalenten Menge Dimethylsulfoxid unter Kühlung zu dem Solvat [MoBr4(OSMe2)2], mit überschüssigem Dimethylsulfoxid entsteht das auch auf anderem Wege zugängliche [MoO2Br2(OSMe2)2]. Molybdändibromiddinitrosyl bildet mit Dimethylsulfoxid das Solvat [MoBr2(NO)2(OSMe2)2]. Nach den IR-Spektren liegen bei allen Komplexen O-Koordination der OSMe2-Moleküle vor. [MoBr2(NO)2(OSMe2)2] kristallisiert monoklin in der Raumgruppe P21/c mit vier Formeleinheiten pro Elementarzelle. Die Gitterabmessungen sind a = 1236, b = 892, c = 1305 pm, β = 95,2° 1662 unabhängige beobachtete Reflexe, R = 3,8%. Das Molybdän ist sechsfach koordiniert, die O-Atome der Dimethylsulfoxidmoleküle befinden sich in trans-Position zu den in gestreckter Bindung koordinierten cis-ständigen Nitrosylgruppen.
