Abstract : In order to explore the feasibility of generating halogen bonding interactions between sulphur-rich π-electron acceptors, we prepared three bithiazolidinylidene derivatives substituted by iodine atoms, namely 3,3′-bis(iodophenyl)bithiazolidinylidene-2,4,2′,4′-tetrathione (BIP-BTTT). Sulphur and iodine heteroatoms were introduced to the skeleton of the acceptor molecule to induce chalcogen...chalcogen and halogen bonding interactions. Both interactions can be evidenced by X-ray diffraction studies in the synthetic precursors as well as in the acceptors themselves.
