Chalcogen Bonding Induced Tetraselenides from Twisted Diselenides
Moulali Vaddamanu, Ganesan Prabusankar
Abstract
The first sterically controlled oxidation of mesoionic selone using copper(II) salt was demonstrated. The present methodology gave access to a rare tetraselenide from dimerized diselenides through chalcogen bonding (ChB). Besides, a similar approach with sterically less crowded mesoionic triazole selone, 1‐(2‐mesitylene)‐3‐methyl‐4‐phenyltriazolin‐5‐selone, gave the classic diselenide salt. In the solid state, these new selenide salts demonstrate a unique structural aggregation with unusual bonding features such as Se ··· O and Se ··· F interactions.
