THE contrasting magnetic behaviour (Table 1 and Fig. 1) of the α- and β-forms of RuCl3 is of interest in relation to the different types of stereochemical arrangements1 shown by the transition metal halides: it has also allowed the presence of α-RuCl3, produced in the usual method of preparation of β-RuCl3, to be detected. A material, hitherto considered2,3 as yet another form of RuCl3, is now shown to be Ru2IVOCl6 (Table 1), a member of a class of oxide chlorides of binuclear ruthenium in which the average oxidation state of ruthenium changes from +4 through +3.5 to +3.
