Dalton Trans., 2003, 3634–3638 (DOI: 10.1039/b305560d). Amendment published 2nd February 2004.

Page 3636. The positions of N3, N4, C17 and C18 in Fig. 3 and Fig. 4 are incorrect. N3 and N4 should change their positions with C17 and C18. The correct figures are presented below. Since the correction does not change the coordinates of atoms, the discussion in the paper is not affected.

The H atoms and crystalline water molecules are omitted for clarity.

  

Re-refinement of the structure results in small changes to some of the values originally presented. Updated Tables 1 and 2S are provided.
