Preparation, Redox Properties, and Structures of Mononuclear „Simple“ Mono-, and Dinitrosyl Complexes of Molybdenum with Hydroxylamido(-1), Oximato, Halogeno, and Pseudohalogeno LigandsThe compounds [(C6H5)4P]2[Mo(NO)(H2NO)(NCS)4] 1, [(C6H5)4P]2 [Mo(NO)((C2H5)2-CNO)(NCS)4] 2, [(C6H5)4P]2[Mo(NO)2(NCS)4] · CH3OH, 3 [(C6H5)4P]3[Mo(NO)(CN)5] · 2H2O 4, Cs2[Mo(NO)Cl4(H2O)] 5 and Cs2[Mo(NO)Cl5] 6 were prepared and characterized by complete X-ray structure analysis. All complexes have a nearly linear MoNO moiety, whereas in the anions of 1 and 2 a pentagonal-bipyramidal, in 3 - 6 an octahedral coordination sphere of Mo is present. Complexes with {MoNO}n configuration (n = 4, 5, 6) can be converted into each other by remarkable redox-reactions. Some novel reactions of the hydroxylamido(-1)-ligand (formation of 2 and 3) are discussed very shortly.
Notes:
Die Verbindungen [(C6H5)4P]2[Mo(NO)(H2NO)(NCS)4] 1, [(C6H5)4P]2-[Mo(NO)((C2H5)2CNO)(NCS)4]2, [(C6H5)4P]2[Mo(NO)2(NCS)4] · CH3OH 3, [(C6H5)4P]3[Mo(NO)(CN)5] · 2H2O 4, Cs2[Mo(NO)Cl4(H2O)] 5 und Cs2[Mo(NO)Cl5] 6 wurden dargestellt und durch vollständige Röntgen-Struktur-Analyse charakterisiert. Alle komplexen Anionen besitzen etwa lineare MoNO-Gruppen, wobei in 1 und 2 eine pentagonalbipyramidale und in 3-6 eine oktaedrische Koordination des Molybdäns vorliegt. Komplexe mit {MoNO}n (n = 4, 5, 6)-Konfiguration lassen sich durch bemerkenswerte Redox-Reaktionen ineinander überführen. Einige neuartige Reaktionen des Hydroxyl-amido(-1)-Liganden (Bildung von 2 und 3) werden kurz diskutiert.
