2. (a) If the W(Cp)2(CO)3 complex follows the 18 VE rule in octahedral geometry, identify the possible hapticity of both Cp ligands. (4 marks) (b) If the complex in (a) follows the 18 VE rule but is not in octahedral geometry, and one Cp ring ligand occupies three spaces, (i). calculate the hapticity of the remaining one Cp ring. (ii). illustrate the signal of the Cp ring mentioned in (i). in the 1H NMR spectrum when the analysis was carried out at 30C and -64 C. (iii). explain your answers in (ii). (10 marks) 2.
