Abstract

Reaction of K[(SePPh₂)₂N] with [Te(tu)₄]Cl₂ (tu = thiourea) in methanol gave [Te{(SePPh₂)₂N}₂], (1), while reaction of K[(SPPh₂)₂N] with 4-MeOPhTeCl₃ in methanol gave [4-MeOPhTe-{(SPPh₂)₂N}]₂, (2). The crystals of 1 are triclinic and contain centrosymmetric molecules. The ligands are bidentate and form a true square planar Te(II) complex with TeSe₄ coordination. For 2, the crystals are also triclinic, and the dimeric molecules are centrosymmetric. Each dithiolate ligand bridges the two Te(II) atoms; the result is a T-shaped coordination around each tellurium atom. A tendency to weak Te-Te bonding across the ring-formed dimer roughly in the direction of the missing fourth ligand in a potential square planar tellurium coordination sphere is also found [Te-Te = 3.761 (1) Å]. In 1, the Te-Se bonds have an average length of 2.797 Å. The Te-S bonds in 2 are quite asymmetric with Te(1)-S(1) = 2.551 (3) Å and Te(1)-S(2a) = 2.873 (3) Å, while Te(1)-C(1) = 2.10 (1) Å.
