Figure 3
A projection of the structure of (I) on to the (001) plane, showing the two-dimensional sheet structure generated by the C—H⋯O contacts of the hydrogen-bonded R12(7) motif. The lattice acetonitrile molecules and tetrafluoroborate anions have been omitted for clarity. Only one set of F atoms (F11A, F12A, F13A and F14A) is shown for each tetrafluoroborate anion (atom types are as depicted in Fig. 2). |
