We have noticed an error in the tabulation of the IR data for complexes ,  and . The experimental highest energy bands for these species in Table 1 should read 2074 cm-1, 2008 cm-1 and 2002 cm-1, respectively, improving the correlation with the calculated values. In the text of the manuscript, the highest energy band data for complex  should again read 2008 cm-1. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
