Acta Crystallographica Section E: Crystallographic Communications, 2021 Ionic co-crystals are co-crystals between organic molecules and inorganic salt coformers. Co-crystals of pharmaceuticals are of interest to help control polymorph formation and potentially improve stability and other physical properties.

Praziquantel Fifty Years on: A Comprehensive Overview of Its Solid State [PDF]
, 2023 This review discusses the entire progress made on the anthelmintic drug praziquantel, focusing on the solid state and, therefore, on anhydrous crystalline polymorphs, amorphous forms, and multicomponent systems (i.e., hydrates, solvates, and cocrystals)

ChemPlusChem, Volume 90, Issue 11, November 10, 2025.This study explores how halogen substitution in benzoic acid coformers affects the structure and stability of carbamazepine cocrystals. Isostructurality and enhanced lattice stability with heavier halogens are revealed, highlighting key supramolecular interactions.

Properadic coformality of spheres
We define a properad that encodes $n$-pre-Calabi-Yau algebras with vanishing copairing. These algebras include chains on the based loop space of any space $X$ endowed with a fundamental class $[X]$ such that $(X,[X])$ satisfies Poincaré duality with local system coefficients, such as oriented manifolds.

Systematic coformer contribution to cocrystal stabilization: energy and packing trends
CrystEngComm, 2020 CSD data mining and energy calculations show that coformer self-interactions might significantly contribute to the packing energy stabilization of cocrystals.

Origin of phase relative stability and phase transformation in an S‐ibuprofen–nicotinamide cocrystal
Acta Crystallographica Section C, Volume 81, Issue 11, Page 658-665, November 2025.The crystal structure of the metastable form of S‐ibuprofen–nicotinamide cocrystals was solved from powder X‐ray diffraction data and explains the main mechanisms responsible for the relative stability of the two forms of the cocrystals. This also made it possible to explain the transition mechanism between the two forms with temperature.The crystal ...

On the rational topological complexity of coformal elliptic spaces
Journal of Pure and Applied Algebra, 2023 We establish some upper and lower bounds of the rational topological complexity for certain classes of elliptic spaces. Our techniques permit us in particular to show that the rational topological complexity coincides with the dimension of the rational homotopy for some special families of coformal elliptic spaces.
