Chimeric supramolecular synthons in PhTe(I)Se.

Iodination of PhTeSe by molecular iodine is directed towards the Te atom and yields {diiodo[(phenyltellanyl)selanyl]-λ-tellanyl}benzene, PhTeSeTeIPh or CHISeTe. The molecule can be considered as a chimera of PhTeSeR, PhTeSeTePh and R'TeIPh fragments. The crystal structure features a complex interplay of the supramolecular synthons Te...π(Ph), Se...Te and I...Te, combining molecules into a three-dimensional framework. Their combination affords long-range supramolecular synthons which are fused in a way resembling the mythological chimera and could be defined as chimeric supramolecular synthons. The energies of the intermolecular interactions have also been calculated and analyzed.
