✦ Synopsis

A series of tetracoordinated organotellurium(IV) compounds with potential immunomodulating properties were studied mass spectrometrically using high-resolution positive ion desorption chemical ionization and constant B/E and B2/E linked-scanning techniques. The nature of the organic ligand bonded to the Te(IV) has a major inÑuence on the mass spectral behavior of these compounds. When only monodentate ligands ÈOR are bonded to the Te(IV), no molecular or protonated molecular ion appears in the spectrum, although polynuclear species are present. When the compounds contain bis-bidentate ligands of the type ÈOROÈ, the protonated molecular ion becomes the base peak and the polynuclear species are not present. 1997
