| Description | Four neutral ligands of the diphosphine disulfide type with different central linking groups [(CH2)4, (CH2)6, (C6H4)2, and HN-(C6H4)-NH] were reacted with 4-methoxyphenyltellurium trichloride in dichloromethane. The crystallization of products afforded crystals consisting of binuclear addition complexes of 4-MeOC6H4TeCl3 with corresponding ligands. The ligands are coordinated to Te(IV) centres through weak Te-S bonds. The coordination of both tellurium atoms in each complex is pseudo-octahedral, built of the TeCl3S tetragonal basis and the aryl group and the lone pair of electrons in axial positions. The weak donating properties of sulfur atoms are reflected in shortening of the trans-positioned Te-Cl bonds. |
