Abstract
MOST complex compounds of cobalt are of oxidation state + 3 and six-co-ordinate, or of oxidation state + 2 and four- or six-co-ordinate. Until recently, only a few apparently five-co-ordinate complexes had been reported1. These were the anions [Co(CN)5]3− and [Co(CN)5]2−, and the oxygen-carry ing Schiff's base compounds (A) and (B).
