Abstract
The 125Te Mössbauer spectra of a number of Te(II) and Te(IV) complexes of thiourea and related derivatives have been measured. The isomer shifts and quadrupole splittings for several of the compounds are interpreted in terms of a bonding scheme utilizing three-center, two-electron bonds in which the tellurium 5p orbitals participate. The 129I Mössbauer spectrum of trans-TeEtu2129I2 is reported and the isomer shift and quadrupole splitting are shown to be consistent with the proposal that the iodine uses only a 5p orbital in bonding to the tellurium.Keywords
