Pyridine boronic acids as building blocks in crystal engineering
Özet
We describe the use of different molecular tectons (building
blocks), which exploit new and related synthons to generate a diverse
range of crystal structures.1,2 In particular salts of protonated pyridine
boronic acids with anionic dithiooxalate complexes are shown to
contain hydrogen-bonded supramolecular complexes which associate
to form motifs of interesting dimensionality and form. Issues
addressed include structural mimicry of one tecton by another,
competition between alternative hydrogen bond acceptors and
robustness of periodic motifs.
