Supramolecular Synthons: Will Giant Rigid Superspheres Do? [PDF]
Crystal Growth & Design, 2016 For the first time, the concept of supramolecular synthons was applied to giant rigid superspheres based on pentaphosphaferrocene [CpRFe(η5-P5)] (R = Me, Et) and Cu(I) halides, which reach 2.1-3.0 nm in diameter. Two supramolecular synthons, σ-π and π-π, are discovered based on halogen···CpR and Cp*···Cp* specific interactions, respectively.

Structural synthon approach to predict the possible polytypes of layered double hydroxides [PDF]
, 2012 The complete universe of possible polytypes of layered double hydroxides (LDH) is predicted on the basis of symmetry arguments. A single MX 2 (X = OH) layer, also defined as a structural synthon, belongs to the layer group P$\bar{3}$2/m1.

Aniline–phenol recognition: from solution through supramolecular synthons to cocrystals
IUCrJ, 2014 Aniline–phenol recognition is studied in the crystal engineering context in several 1:1 cocrystals that contain a closed cyclic hydrogen-bonded [...O—H...N—H...]2 tetramer supramolecular synthon (II). Twelve cocrystals of 3,4,5- and 2,3,4-trichlorophenol

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.

Designing Supramolecular Gelators: Challenges, Frustrations, and Hopes
Gels, 2019 This article is a personal account of the author, who serendipitously entered the field of supramolecular gels nearly two decades ago. A supramolecular synthon approach in the context of crystal engineering was utilized to develop a working hypothesis to
