Crystals at a Carrefour on the Way through the Phase Space: A Middle Path
Molecules, 2021 Multiple supramolecular functionalities of cyclic α-alkoxy tellurium-trihalides (including Te---O, Te---X (X = Br, I) and Te---π(C=C) supramolecular synthons) afford rich crystal packing possibilities, which consequently results in polymorphism or Z’ > 1

Cocrystal of 4-Nitrophenol and 2,1,3-Benzoselenadizole
Molbank, 2023 The 1:1 cocrystal of 4-nitrophenol (NP) and 2,1,3-benzoselenadiazole (BSA) was successfully synthesized. The X-ray single-crystal diffraction analysis revealed that the structure contained a [Se–N]2 cyclic supramolecular synthon.

Supramolecular synthons and crystal structure prediction of organic compounds [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2004 The strategy taking into account regularities of crystal structure formation and results of theoretical crystal structure prediction has been proposed as a tool for crystal engineering. The role of the symmetry of the supramolecular associates (synthons) in the symmetry of the crystal structure is suggested.
