Abstract
An approach to tackle the synthesis of mixed-transition metal tantalum chalcogenide clusters is described. The synthesis of 1/(infinity)[Li-3(TaSe4)(MeCN)(4)](infinity) (1) will in future allow the construction of Ta-Se-transition metal clusters. The potential of this route was demonstrated by the synthesis of the mixed-metal Ta-S-Fe and Ta-S-Cu complexes (Et4N)(3)[Fe-2(SPh)(4)(TaS4)] (2) and [Cu-3(TaS4)(PPh3)(4)] (3).
