Propose an 18e- structure for the following metal/ligand combinations. Use at least one of each metal and ligand listed. Complexes must be neutral. Don't use more than 2 metal centers. Show your electron counting. Ligands are shown without charges, please indicate the proper ligand charge in your electron counting. Draw a reasonable structure showing the geometry about the metal center(s). a) Ir, Cp, H, PMe3 b) Rh, dppe (chelating), μ-CO, HC=CH c) Mo, Cp, CH3, N=CMe d) Pt, dmpm (bridging), μ-CO (only one), CO 5) Arrange following phosphine ligands starting prom a phosphine with smaller cone angle to larger one. PEt3, PPh3, P(OMe)3, PH3, PBZ3 6) Arrange following phosphine ligands starting prom the best electon donor to the worst one. PMe3, PC13, P(Et)2(OMe), P(OEt)3, P(iPr)3 7) According to IR shifts arrange the metal complexes from most electron rich to the most electron deficient metal center. Which complex will be the most stable? Co(CO)4 1890, Ni(CO)4 2060 cm³, Fe(CO)4² 1790 Explain your answer. Propose an 18e- structure for the following metal/ligand combinations.
