Synthesis and structure of the new cubane-like cluster [Fe4Te4(PEt3)4]PF6, containing only terminal phosphine ligands
Abstract
The cubane-like [Fe4Te4(PEt3)4]PF6 and the stellated octahedron [Fe6Se8(PEt3)6]PF6 clusters have been obtained by reaction of Fe(ClO4)2 with PEt3 and H2X (X = Te, Se), in the presence of PF6–; a crystal structure of the tellurium derivative has been determined.
