SAIC Pr7.1 The compound Na,lrCl, reacts with triphenylphosphine in diethyleneglycol in an atmosphere of CO to give trans-[IrCI(CO)(PPH3)], known as "Vaska's compound'. Excess Co gives a five coordinated species and treatment with NaBH in ethanol gives [IrH(CO)2 (PPH3)2]. Derive a formal name for 'Vaska's compound'. Draw and name all isomers of the two five-coordinate complexes.

(d) Exchange of H₂O for D₂O in [Cr(H₂O)]³+ is extremely slow (k = 2.6 x 10-6 s-¹ at 25°C), while for [Cr(H₂O)]²+ it is very fast (k = 1.2 x 108 s1 at 25°C). Account for these observations and suggest the most likely electronic configuration of [Cr(H₂O)6]²+.
When dimethoxyethane reacts with I+, it forms a Lewis acid-base complex in which both oxygens bond to the iodine. What is the electron group geometry (from VSEPR theory) of the complex?

[Rh(PPh3)3Cl] is a precatalyst that can be activated by dissociation of a phosphine ligand to form an active catalyst, B, which is used in the hydrogenation of alkenes. The active catalyst can then undergo oxidative addition in the presence of H2 to form complex C. Propene coordinates to C to form complex D, which then undergoes a 1,2- insertion step to form E. Reductive elimination of propane from E regenerates the active catalyst B. Draw complexes B – E and hence provide a full catalytic cycle, including the activation step, for the hydrogenation of propene
