Iodophosphane Selenides: Building Blocks for Supramolecular Soft-Soft Chain, Helix, and Base-Pair Arrays
摘要:
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 [tBu(2)P(Se-I-I)I](2) that are interconnected by additional Se ... Se contacts.
