A doubly bridging (η 2 ,μ 2 ,μ 2 Te 4 ) 2− ion and a bridging [TeCl 2 ] 2+ ion with a nearly linear ClTeCl angle are the prominent structural features of complex 1 (shown on the right, CO ligands on Fe have been omitted), which contains both oxidized and reduced tellurium centers in the same molecule. This complex is stabilized through weak Te – Te interactions forming infinite sheets in the solid state, but is not stable in solution. Complex 1 is the ultimate product of a complex halogenation of [Te 2 Fe 3 (CO) 9 ].
