20. -3. The data collection was done at 293 K using graphite monochromated Mo-Ka radiation (λ= 0.71069 Å). The structure was solved by direct methods (SHELXS86) and refined by full-matrix least-squares techniques (SHELXL93) to R = 0.070 (Rw = 0.206) for 1730 independent reflections having I > 2σ(I). Due to the disorder of the tert-butyl group and the large thermal parameters of the side-chain terminals, the structure data are not good enough to discuss the bond lengths and angles in detail. However, the crystallographic analysis certainly confirms the novel hydrogen-bonded dimer structure. Full crystallographic details are deposited in the Cambridge Crystallographic Data Centre.
