Carbonyl Complexes Possessing Column Structures

However, these compounds exhibit smaller conductivities compared to non-stoichiometric iridium complexes because the band is completely occupied. Moreover, the overlap of orbitals in those rhodium complexes is less effective than in iridium compounds.

Column structures have also been determined for carbonyl complexes of rhodium, iridium, and platinum. For platinum complexes of the formula [Pt3(CO)6] , the maximum value of n probably does not reach more than 20 (Figure 3.26) and therefore these carbonyls do not show anisotropy of conductivity. Various Ir(I) and Rh(I) complexes possessing column structures are known [IrX(CO)3] (X = C1, Br, I), [IrCl,o7(CO)2.93], [Ir(acac(CO)2], Ho.38lrCl2(CO)2(H20)2.9, Ko.58[IrCl2(CO)2], and...
