✦ Synopsis

The reported [3] I: 1 O2 absorption by RuC12-(AsPh& must be due to oxidation of 2 mol of coordinated arsine in complexes such as those listed above. The so-called 880 cm-' peroxide band is attributable to VA-, and the paramagnetism and esr signals (assigned to a Ru"'-O; moiety) are likely due to Ru(II1) arsine oxide complexes, which are known [ 121. Infrared data ascribed [3] to reaction (2) may be accounted for by the
