Fig. 3. Alternative representations of the iron–tellurium cuboidal core of 1 as (a) an [4Fe–4Te] hexahedron showing 12 × Fe–Te bonding interactions, and (b) a compound of smaller [4Fe] and larger [4Te] tetrahedra showing 6 × Fe···Fe and 6 × Te···Te nonbonding interactions. The internuclear distances are characterized in subsets of ‘long’, ‘intermediate’, and (optionally) ‘short’, with (c) their mean values in the respective polyhedra given as found in the X-ray/DFT-optimized structures. For a detailed account of these distances, see ESI Table S2.† Broken-symmetry (BS) spin alignment (↑ or ↓) of the [4Fe] sites applied in the DFT solution is shown in (b).
