Abstract
Complexes [RC5H4Fe(CO)2]2Sn(TePh)2 (R = H, Me) containing stable heterometallic Fe - Sn - Fe fragments with two phenyltellurium groups at the tin atom were synthesized from [RC5H4Fe(CO)2]2SnCl2 (R = H, Me) and sodium phenyltelluride and their structures were established by X-ray analysis. Their chelates with tungsten tetracarbonyl, [RC5H4Fe(CO)2]2Sn(TePh)2[ W(CO)4] (R = Me, H), and complexes with two Cr(CO)5 fragments or dimeric trimethylplatinum iodide were synthesized and studied by X-ray analysis. Thermal decomposition of [RC5H4Fe(CO)2]2Sn(TePh)2 complexes and their adducts with ML fragments (ML = W(CO)4, 2 Cr(CO)5, (Me3PtI)2) into inorganic tellurides of a preset mixed-metal - chalcogenide composition was studied by differential scanning calorimetry. The temperature of complete elimination of organic fragments from methylcyclopentadienyl complexes is about 100 °C lower than in the case of cyclopentadienyl analogs.
