Angew Chem Int Ed Engl. 1999 Apr 1;38(7):931-933. doi: 10.1002/(SICI)1521-3773(19990401)38:7<931::AID-ANIE931>3.0.CO;2-B.

Abstract

Anions PF6- and CF3 SO3- 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- , CF3 SO3- ). hat-(CN)6 =hexaazatriphenylene hexacarbonitrile; dppe=1,2-bis(diphenylphosphanyl)ethane.
