Chalcogen bond

{
  "id": "MLC-T-CHM-001863",
  "term": "Chalcogen bond",
  "field": "Chemistry",
  "definition": "A noncovalent interaction occurring when an electrophilic region on a covalently bonded chalcogen atom (sulfur, selenium, tellurium, or polonium) interacts with a nucleophilic region on another atom. This interaction is directional and can be attractive, similar to a hydrogen bond or halogen bond. The strength of the chalcogen bond increases with the polarizability of the chalcogen atom.",
