Summary

The magnetic susceptibility of MoO(OH)3 or [MoOF5]2− in HF has been measured as a function of acid concentration. In very dilute acid the solutions are diamagnetic. The anionic complexes K4[Mo2O4F6] · 2H2O, K3[Mo2O4F5], Cs4[Mo2O4F6], Cs2[Mo2O4F4], (bipyH)2[Mo2O4F4] and (phenH)2[Mo2O4F4] were prepared by adding fluoride to solutions of MoO(OH)3 in dilute HF. The bipyridyl and phenanthroline compounds are converted to the nonelectrolytes [Mo2O4(bipy)2F2] and [Mo2O4(phen)2F2], respectively, on digesting with water or heating. These complexes are also obtained by adding the respective diimines to solutions of K2[MoOF5]. All the complexes are very weakly paramagnetic. The i.r. and the electronic spectra of the compounds show the characteristic features of complexes containing the Mo2O 4 +2 moiety.
