Abstract
The new compound Cu2I(TCNQF4 II-)(MeCN)2 (TCNQF42- = dianion of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane) has been synthesized by electrochemically directed synthesis involving reduction of TCNQF4 to TCNQF42- in acetonitrile containing [Cu(MeCN) 4]+(MeCN) and 0.1 M Bu4NPF 6. In one scenario, TCNQF42- is quantitatively formed by reductive electrolysis of TCNQF4 followed by addition of [Cu(MeCN)4]+ to form the Cu2 I(TCNQF4II-)(MeCN)2 coordination polymer. In a second scenario, TCNQF4 is reduced in situ at the electrode surface to TCNQF42-, followed by reaction with the [Cu(MeCN)4]+ present in the solution, to electrocrystallize Cu2I(TCNQF4 II-)(MeCN)2. Two distinct phases of Cu2 I(..
