Structural and Spectroscopic Studies of Rhodium-(I) and -(III) Nitrato Complexes

Refluxing Rh(NO3)3*2H2O with an excess of PPh3 in MeOH or EtOH for over 48 h gives trans- 1 whereas the same reaction at room temperature gives predominantly 2.X-Ray structure determinations of 1 and 2 show the nitrate groups to be monodentate in each case although disorder of the CO and NO3 groups in 1 precludes accurate determination of bond lengths and angles.There is no reaction of trans- (X = Cl, F or ONO2) with H2 at room temperature and 1 atm pressure, whereas there is an intermediate reaction of under the same conditions to give 3, which has been characterised by multinuclear NMR spectroscopy.Compound 3 loses PPh3 to give 6a which has been characterised similarly and by X-ray crystallography; although the metal-bound hydrogens were not located the structure is clearly based on an octahedral geometry with trans phosphines and a bidentate nitrate.
