cetyl]aminoethoxy}-26,28-dihydroxycalix[4]arene} were studied by electrospray mass spectrometry. When La was refluxed with 2.2 equiv. of trans-[Pd(Py)2Cl2] or 1.1 equiv. of PdCl2, the mononuclear complex PdLaCl2 was formed. When refluxed with 2.2 equiv. of PdCl2, the binuclear complex Pd2LaCl4 was obtained. The same binuclear complex Pd2LaCl4 was also obtained as the final adduct when Lb was refluxed
