Abstract

Starting from molybdenum trioxide 2,2′-bipyridinium oxopentachloromolybdate(V) BipyH2[MoOCl5] has been isolated in pure state as greenish yellow crystalline solid. From this salt the nonelectrolytic paramagnetic complex MoOCl3·bipy has been isolated in three different isomeric (colored reddish pink, pale khaki and green) forms by dehydrohalogenation in suitable solvent and solid state reaction. The diamagnetic complex Mo2O4Cl2(bipy)2 has been isolated by hydrolysis of the parent salt. All these products and the parent salt have been shown to be interconvertible. The constitution of expected cis-trans isomers of MoOCl3·bipy has also been discussed. All these compounds have been studied by various physicochemical methods and it has been shown that the oxometal entity MoO3+ remains intact under various chemical environments.

    The main bands in the IR spectra (ν(MoO), ν(MoCl) and the strong bands of the diimine) were essentially identical to those in the red isomer, and in addition, some of the spectra (but not all) showed other weaker bands, absent in the spectra of the red isomer (S3, S13). Very similar spectra for the two ‘isomers’ are also reported in the literature, although data quality are variable with doubts about the purity of some samples raised by other authors, and often data below 500 cm−1 were not reported [22–26,39]. As would be expected from the different colours, the greatest differences are in the UV/visible spectra.

    Comparatively, Mo(V) complexes have been less discussed due to their instability. The chemistry of Mo(V) is dominated by the paramagnetic mononuclear molybdenyl cation MoO3+ and diamagnetic binuclear oxo-bridged Mo2O34+ or Mo2O42+ cores [8–14]. The treatment and eradication of cancer involves chemotherapy as one of the important techniques [15].

    We believe a more likely explanation of the maroon color is the non-oxo Mo(IV) complex MoCl4(PEt3)2. This would be closely related to the Mo(III) anion MoCl4(PEt3)2 − already observed in this system, and other trans-MoCl4(PR3)2 complexes have been reported to be maroon [37,44], though no electronic absorption spectral data have been published. Thus, PEt3 reacts with Mo(V) to give the oxygen atom transfer products of Scheme 1, and other products.
