Consecutive treatment of Fe2Se2(CO)6 with anhydrous tin dichloride and sodium phenyltelluride in ethanol has produced dark red crystals of the heterometallic cluster Sn[Se2Fe 2(CO)6]2 (IV). The cluster has been characterized using X-ray crystallography. The complex has a spirane structure with a central tin atom tetrahedrally surrounded by four selenium atoms (Sn-Se 2.539(2)-2.549(1) Å); selenium atoms are linked in pairs to two Fe 2(CO)6 fragments (Fe-Se 2.401(1)-2.418(1) Å) with bond lengths Fe-Fe 2.544(2) and 2.521(2) Å. Upon thermolysis, Sn[Se 2Fe2(CO)6]2 eliminates all carbonyls yielding mixed-metal selenide SnSe4Fe4.
