Figure 4
A view of the hexagonal packing adopted by the cylindrical biadamantanediyl groups (C-bound H atoms have been omitted for clarity), showing how three closest neighbours assemble into hydrogen-bonded triads (dashed lines). Triads from two adjacent biadamantanediyl layers form the hexamer. [Symmetry code: (iii) −x + 1, −y, −z.] |
