Structure determinations on di-tert-butyliodophosphane selenide 1 and c- hexyldiiodophosphane selenide 2 reveal that intermolecular donor-acceptor interactions between nucleophilic selenium atoms and electrophilic iodine atoms lead to chains or helices that are interconnected by Se ··· Se contacts, building up layer structures. In the adduct of 1 with molecular iodine (3), 1 acts as donor through Se(=P) and as weak acceptor through I(- P). These interactions lead to base-pair-like dimers [tBu2P(Se-I-I)I]2 that are interconnected by additional Se ··· Se contacts.
