The reactions of a series of Cu(I) and Cu(II) complexes containing pyrazolyl or dimethylpyrazolyl residues in the ligands during the ionization process were studied by fast atom bombardment mass spectrometry. Complexes with a +1 charge produce intact cations. Those with a higher charge yield +1 cations by formal reduction or by clustering with anions, sometimes by several simultaneous processes. Neutral complexes are protonated to give +1 ions.
