The preparation and structure of (SeCl2)2N+AsF6–·MeCN containing the first ternary selenium, nitrogen, chlorine cation

Abstract

The Cl₂Se–N–SeCl₂⁺ cation which represents the first example of a ternary Se, N, Cl species has been prepared by the reaction of SeCl₃⁺AsF₆^– and N(SiMe₃)₃; the crystal structure of the AsF₆^– salt has been determined by a low-temperature single crystal X-ray diffraction study.
