As a result the authors also wish to include the following in their results and discussion section: Note that, compound 1 has been synthesized and structurally characterized by Grimes and co-workers in a different synthetic pathway ( J. Am. Chem. Soc., 1977, 99, 5646; Inorg. Chem., 1977, 16, 3251).
