Synthesis, characterisation and crystal structure of a dirhodium(II) compound with two bridging trifluoroacetamidate ligands
Abstract
The compound [Rh2(HNCOCF3)4] reacts with 1,10-phenanthroline (phen) in the presence of HCI to give two isomers of [Rh2(HNCOCF3)2(phen)2Cl2], 1a and 1b, which are readily distinguished by 1H NMR spectroscopy. In contrast if the reaction is carried out in the presence of a non-acidic chloride source, tetrabutylammonium chloride, only a single isomer, 1a, is formed in appreciable amounts. Complex 1a reacts with pyridine in the presence of K[PF6] to give [Rh2(HNCOCF3)2(phen)2(C5H5N)2][PF6]2, 2, which has been characterised by X-ray crystallography. For comparative purposes [Rh2(O2CCH3)2(phen)2(C5H5N)2][PF6]2, 3, has been prepared and crystallographically characterised.
