9. The figure below shows the distributions of equatorial ligands, the distances of three Ru-Ru bond and bond angles in Rus(CO) 12. obtained from its single- crystal X-ray diffraction 04 10024 R. os 1050 Ruz Au 20 10.0 188 08.04 023 Figure 1 If two co ligands in Figure 1 are substituted with a 1,1- bis(diphenylphosphino)methane, (a) Predict the bond distances of three Ru-Ru bonds. (6 marks) (b) Predict the bond angles. (6 marks) (c) Explain the two main differences, in term of geometry parameters, between Figure 1 and complex stated in (a)(). (6 marks) (d) Substitution reactions of Figure 1 with monodentate and bidentate ligands yield new trisubstituted complexes, where the trinuclear core of Rus structure remains unchanged.
