Abstrakt: An intermediate in the ethanolysis reactions of MoCl5, [MoOCl3(EtOH)] 2, has been isolated after the reaction of MoCl5 with 2 equivalents of EtOH and its crystal structure was determined. Treatment of MoCl5 with 2.5 equivalents of EtOH and subsequent cooling as well as the reaction of [Cl2OMo(-OEt)2(-HOEt)MoOCl2] 1 with HCl(g) yield a product which has been identified as H[MoOCl4]·2EtOH 3 by X-ray crystallography. The mechanisms leading to 1–3 are discussed. The reactions of 2 with donors have been investigated and [Cl2OMo(-OPr)2(-HOPr)MoOCl2] 4 was obtained as a first derivative of 1 after the reaction of MoCl5 with PrOH.
