Fig. 6.35. Schematic energy-level diagram for the 3d orbitals in C09S8 showing a conduction band formed through metal-metal interactions between tetrahedral-site cobalt atoms [ct M(T)] and metal-sulfur-metal interactions to octahedral-site cobalt atoms [ct M(0)] (after Prewitt and Rajamani, 1974 reproduced with the publisher s permission).

Finally let us also localize the unoccupied delocalized MO s i//J to 4 of Fig. 27 and Table 3. Since they are generated from an s and three p GO s, the appropriate hybrid GO s clearly are sp3. The resulting localized MO s are most easily visualized as cobalt sp3 hybrids directed towards four of the eight octahedral faces and having antibonding interactions with the three fluorines on the comers of that face. In Fig. 29 is shown an energy level diagram in which the above considerations are reflected. 

Figure 12.5 Plots of the experimentally determined structures of the hexacoordinate, s = 0, (a) and pentacoordinate, s= 1, cobalt(lll) (b) complexes, an energy level diagram (c) based on DFTcalculations, the steric strain (d) and the HOMO-LUMO gap (e) as a function of the angle shown in (d) [474].

The electronic structures of iron, cobalt, nickel, and the platinum metals are given in Table 19-1, as represented in the energy-level diagram of Figure 5-6. It is seen that each of the atoms has two outermost electrons, in the 4s orbital for iron, cobalt, and nickel, the 55 orbital for ruthenium.
