Chimeric supramolecular synthons in Ph2Te2(I2)Se

Research output: Contribution to journalArticlepeer-review


Iodination of Ph2Te2Se by molecular iodine is directed towards the Te atom and yields {diiodo[(phenyltellanyl)selanyl]-λ4-tellanyl}benzene, PhTeSeTeI2Ph or C12H10I2SeTe2. The molecule can be considered as a chimera of PhTeSeR, PhTeSeTePh and R′TeI2Ph 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.
