Abstract

Oxo-Mo(VI) imido-chloride, [MoOCl2(NH)(Et 2O)] n and nitrido-chloride, [Mo2O2Cl2(N)2(Et 2O)] n have been synthesized by equimolar reactions of MoOCl4 with HN(SiMe 3)2 and LiN(SiMe 3)2, respectively. Higher molar reactions of HN(SiMe 3)2 lead to imido-silylamido derivatives, [Mo2OCl3(NH)3(NHSiMe 3)] n , whereas those of LiN(SiMe 3)2 give silylimido bridged compounds, Mo4O4Cl4(NSiMe 3)6 and Mo4O4(NSiMe 3)8. Elemental analyses, redox titration, magnetic moment, molecular weight, molar conductance, infrared,1H-NMR and TG-DTG-DTA studies are reported.

Zusammenfassung

Durch equimolare Reaktionen von MoOCl4 mit HN(SiMe 3)2 und LiN(SiMe 3)2 wurden die Oxo-Mo(VI) Imido-chloride [MoOCl2(NH)(Et 2O)] n und die Nitrido-chloride [Mo2O2Cl2(N)2(Et 2O)] n dargestellt. Höhermolekulare Reaktionen von HN(SiMe 3)2 führen zu Imido-silylamido Derivaten [Mo2OCl3(NH)3(NHSiMe 3)] n , währenddessen die von LiN(SiMe 3)2 silylimidoüberbrückte Verbindungen ergeben: Mo4O4Cl4(NSiMe 3)6 und Mo4O4(NSiMe 3)8. Die Strukturen sind mit Elementaranalysen, Redoxtitrationen, Messung der magnetischen Momente, Molekulargewichten, molarer Leitfähigkeit, Infrarot,1H-NMR und TG-DTG-DTA-Untersuchungen charakterisiert.
