A New Anion-Trapping Radical Host, [(Cu-dppe)3{hat-(CN)6}]2+

Anions PF6− and CF3SO3− are trapped by the new radical host [(Cu-dppe)3{hat-(CN)6}]2+, which was synthesized in a one-pot reaction from a copper(I) source, hat-(CN)6, and dppe in acetone. The trapped salts have been characterized both in solution and in the solid state (see picture: A−: PF6−, CF3SO3−). hat-(CN)6=hexaazatriphenylene hexacarbonitrile; dppe=1,2-bis(diphenylphosphanyl)ethane.
