L.; Purrello, R.; Lauceri, R.; Sciotto, D.; Gulino, F. G.; Pavone, V. Angew. Chem., Int. Ed. 2001, 40, 4245-4247). Data collection was performed at the XRDI beam-line of Elettra Synchroron. Trieste (Italy). Crystal structure data have been deposited with the Cambridge Crystallographic Data Centre, CCDC No. 202688.
