VASKA (1) has characterized a simple synthetic molecular oxygen carrier O2IrCl(CO)[P(C6H5)3]2 prepared by the addition of molecular oxygen to IrCI(CO)[P(C6H5)3]2 in benzene solution. This synthetic oxygen carrier, which is a reasonably stable crystalline solid, differs from most reported in the past in that there is but one molecule of oxygen per metal atom, as there is in oxyhemoglobin. The mode of attachment of oxygen to iridium in this cornpound is thus of interest both in itself and especially in relation to theories of the mode of attachment of molecular oxygen to the iron atom in oxyhemo — globin.
