A novel mixed valence iodide bridged Te(II)-Te(IV) complex featuring diisopropyldithiocarbamate(L) and iodide: ILTeII(I)TeIVL2I

Te⋯I secondary-bonding interactions in crystals containing tellurium(ii), tellurium(iv) and iodide atoms: supramolecular aggregation patterns, nature of the non-covalent interactions and energy considerations

“…Following these criteria, there are seven examples of mixed tellurium( ii ), tellurium( iv ) and iodide crystals, while each of these featured Te⋯I interactions one of the crystals saw these operating in concert with I⋯I interactions. 94 There are 71 examples of crystals containing tellurium( ii ) and iodide of which 15 (21%) contain Te⋯I interactions operating independently of other, structure-directing non-covalent interactions while there are 129 crystals containing tellurium( iv ) and iodide, 69 (54%) exhibit Te⋯I interactions operating independently of other obvious directional non-covalent interactions. These data suggest that tellurium( ii ) compounds are less likely to form Te⋯I interactions than tellurium( iv ) compounds.…”
