ELEMENTS OF THE CRYSTAL STRUCTURE OF A SOLVATED 1:1 CHARGE-TRANSFER SALT DERIVED FROM TETRATHIAFULVALENE (TTF) AND TETRAFLUOROTETRACYANO-p-QUINODIMETHANE (TCNQF4), TTF-TCNQF4.

The 1:1 charge-transfer salt TTF-TCNQF4 crystallizes (from cyclohexane/acetonitrile) in the monoclinic system, space group P2/m, with a equals 16. 562(4) A, b equals 10. 728(4) A, c equals 7. 013(1) A, beta equals 97. 39(2) degree , V equals 1235. 6 A**3. A structural solution has been obtained by Patterson-Fourier methods and refined (based on 2107 non-zero F//0's) to an R value of 0. 18. The crystal structure of solvated TTF-TCNQF4 consists of segregated stacks of donors and acceptors propagating along the c axis. Parallel to these columnar arrays are solvent channels of unresolved composition. Disorder within these solvent channels prevents a detailed description of their contents; the basic elements of the donor and acceptor stacks are, however, well-defined. The TCNQF4 acceptor column is both distance and overlap modulated (eclipsed, dimeric interaction at a mean separation of 3. 25 A, and ring-over-bond, monomeric interaction at 3. 43 A). The TTF donor column shows analogous eclipsed and ring-over-bond overlap patterns; however, the distance alternation (3. 49 A and 3. 51 A, respectively) is within experimental error ( plus or minus 0. 02 A in each case).
