Subject with oxygen donor atom

The mode of 02 coordination was for some time a subject of controversy. It now seems settled that the ligand molecule is bonded via one O atom, with an Fe-O-O angle of c. 120°. This is consistent with the prediction of a rather crude VB description of the 02 molecule, which allocates two lone pairs to each atom the valence state of O is (sp2)2(sp2)2(sp2)1(p)1. This description is inconsistent with the observed paramagnetism of 02 (which can readily be explained in terms of MO theory). However, oxygenated haemoglobin Hb.402 is diamagnetic and we may fairly describe the Fe-0 bond in terms of a filled sp2 hybrid donor orbital from the O atom. [Pg.357]
