Summary Oxygenation of [Co(pd)2(H2O)2] (Hpd = 2,4-pentanedione) in the presence of triphenylphosphine forms [Co(pd)3] and a peroxo-complex that shows strong v(O-O) at 865 cm−1. The mechanism of Co-pd cleavage and the concomitant formation of [Co(pd)3] are discussed. With guanidine carbonate the title compound forms a carbonato-complex, (CH5N3H)2-[Co(CH5N3)(CO3)2] · H2O, which is the violet component of the so-called blue-violet pair of the complexes of the general formula [CoA2(CO3)2]2− (A2 = ethylenediamine or 2NH3). The carbonato-complex is assigned either a square-pyramidal geometry with monodentate CH5N3 or a polymeric octahedral structure with a bridging CH5N3 group.
