Polymorphism and Supramolecular Isomerism: The Impasse of Coordination Polymers

Abstract

The chapter presented hereafter, outlines the narrow link between chemistry and crystallography that impelled the identification of polymorphism and provided a priceless grounding to understand structure-properties relationship. It was initially conceived for organic substances but actually embraced by metal–organic products, especially in the study of coordination polymers. All of the technologic advances have provided profound insights on the control of crystal structures formation revealing that any applied stimulus over a substance can undergo a structural transformation. This has led to the implementation of several methodologies in the industrial and academic segment shedding light on the source of hitherto, not well understood results.

Polymorphism and isomorphism in trans-bis(2,5-diiodopyridine)dihalocopper(ii) complexes: theoretical and crystallographic studies

“…Solid-state polymorphism, which is due to different arrangements of crystalline species within the crystalline lattices, is one of the most intriguing phenomena in solid state chemistry. 23–26 Polymorphism may be attributed to the crystallization of different conformers or enantiomers, 24,25,27 or different packing of the crystalline units inside the crystalline lattice. 25,28 Different polymorphs have different physical properties including solubility, magnetic and optical properties.…”

Resolvable polymorphism in an intergrowth of two modifications of tris(diethyldithiocarbamato)antimony

“…Experiments were carried out at 100 K with Mo K radiation using a Rigaku SuperNova diffractometer. Absorption was corrected for by multi-scan methods (CrysAlis PRO;Rigaku OD, 2020). H-atom parameters were constrained.…”
