Abstract

The synthesis of a (Te,S) ligand 4-MeOC6H4TeCH2CH2SEt (L) and its complex [PdCl2L] is followed by single crystal structure determination of the complex, which indicates that the Pd–Cl bond length trans to the ArTe group [2.344(3) Å] is longer than that trans to SEt [2.316(4) Å], suggesting a stronger trans influence for the former.
