Comparison of structures and energies of CH(5)(2+•) with CH(4)(+•) and their possible role in superacidic methane activation

Contrary to previous theoretical studies at the UHF/6-31G* level, the methonium radical dication CH(5)(2+) is not a C(s) symmetrical structure with a 2e—3c bond but a C(2v) symmetrical structure 1 with two 2e—3c bonds (at the UHF/6-31G**, UMP2/6-31G**, and UQCISD(T)/6-311G** levels). The C(s) symmet...
