Competition of chalcogen bond, halogen bond, and hydrogen bond in SCSHOX and SeCSeHOX (XÂ =Â Cl and Br) complexes

► The SCSHOX and SeCSeHOX (X = Cl and Br) complexes have been investigated. ► There is competition between chalcogen bond, halogen bond, and hydrogen bond. ► The dispersion interaction plays a dominant role in three types of interactions.
