Synthesis and characterization of three coordinate T-shaped complexes of tellurium (II) incorporating a naphthyl tellurium fragment
2006
Several new three coordinate tellurium(II) complexes have been prepared by the addition of dinaphthyl ditelluride (C10H7)2Te2 and a halogen (Br2 or I2) to various monodentate ligands known to coordinate through their terminal sulfur or selenium atoms to investigate possible electronic and steric effects associated with a large aryl group. Complexes of the type RTeX(L) are described here [R = naphthyl, X = Br, I, L = thiourea (I (X = Br), II (X = I)), tetramethylthiourea (III), selenourea (IV), tris(dimethylamino)phosphane selenide (V) and N-methylbenzothiazol-2(3H)-thione (VI)]. Evidence of the formation of new complexes is presented through microanalytical data and multinuclear NMR spectroscopy in addition to single crystal X-ray diffraction studies of (I) and (III). Structures are described in detail along with a comparison with related Te (II) complexes.
