Co(CO)4]- [Co(CO)4]2 + 2e E%s = 0.4 volt but the salts are much more stable than the parent acid. Structurally, the central cobalt atom is surrounded tetra-hedrally by four C=0 groups,5 with the hydrogen in the hydride lying in one face of the tetrahedron and being bonded to three C O groups.11-13 Precipitation of the cobalt tetracarbonyl anion as the tris(l,10-phenanthroline)-nickel(II) salt is the basis of a method of determining the species.14...
