Abstract
A series of compounds of composition A[Cu (F TCNQ )] (A = a quaternary ammonium or phosphonium cation, F TCNQ = the dianionic form of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane) have been synthesized and structurally characterized. In each structure, an anionic [Cu (F TCNQ )] framework possessing the topology of PtS is formed with the Cu(I) center serving as a tetrahedral 4-connecting center and the F TCNQ anion acting as a planar 4-connecting unit. Although a PtS topology is observed for six different compounds, the anionic framework shows significant geometric variation depending upon the identity of the cation. Very similar structures are obtained when the organic cation is..
