Reactivities of the chalcogen-capped triiron clusters [EFe3(CO)9]2– (E = Te, Se, S): cluster growth and transformations

Copper Halide-Incorporated Tellurium−Iron Carbonyl Complexes: Transformation, Electrochemical Properties, and Theoretical Calculations

“…The previous study showed that the tellurium-capped tri-iron carbonyl complex, [TeFe 3 (CO) 9 ] 2− , exhibited an interesting affinity toward organic and inorganic electrophiles. ,− Recently, we have reported a series of copper halide-incorporated triiron selenide carbonyl clusters from the reaction of [SeFe 3 (CO) 9 ] 2− with CuX (X = Cl, Br, I) . Along this line, we attempted to extend our work into whether [TeFe 3 (CO) 9 ] 2− could be used as a building unit for further metal expansion reactions. It has been shown that [TeFe 3 (CO) 9 ] 2− can be linked by Cu + cations to give a novel ternary semiconducting Te−Fe−Cu polymer .…”

“…In contrast to sulfur- and selenium-transition metal complexes, tellurium-containing transition metal complexes have attracted much attention, particularly because of the pronounced effect of the Te element on the entire metal skeleton. , However, study into the potential use of tellurium as a stabilizing ligand for metal clusters has been limited, and its use in their formation has been scarce. Previous studies on tellurium-containing iron carbonyl clusters have focused on their synthesis and structural features. − Thus, the ability of these complexes to function as building blocks for metal expansion reactions in terms of the effect of tellurium and transition metals is of great interest and is a challenge because of their potential uses in the preparation of mixed metal nanoparticles in nanotechnology …”
