Abstract

original image

Even the metal–ligand coordination in the molecular square 1 is retained in the fragments generated by fast atom bombardment in the mass spectroscopic method described. In this example the M–2OTf peak can be identified unequivocally owing to the peak separation of 0.5 m/z units in the isotopic distribution pattern.
