Triangular halogen-halogen-halogen interactions as a cohesive force in the structures of trihalomesitylenes

TL;DR: The σ-hole and π-hole are the regions with positive surface electrostatic potential on the molecule entity; the former specifically refers to the positive region of a molecular entity along extension of the Y-Ge/P/Se/X covalent ρ-bond.

TL;DR: Using results from database mining, this review attempts to give an overview of types and structural features of these previously rather overlooked interactions of multipolar interactions in organizing a crystal lattice or stabilizing complexes involving biological receptors.

TL;DR: Both chemical and geometrical models need to be considered for X...X interactions in hexahalogenated benzenes, where nonspecificity of the weak interlayer interactions here is demonstrated by the structure of twinned crystals of these compounds.

TL;DR: From molecular to supramolescular chemistry: concepts and language of supramolecular chemistry, molecular recognition, information, complementarity molecular receptors - design principles and more.

TL;DR: In this article, the authors show that crystal engineering is a new organic synthesis, and that rather than being only nominally relevant to organic chemistry, this subject is well within the mainstream, being surprisingly similar to traditional organic synthesis in concept.

TL;DR: In this article, a review of solid-state photochemistry can be found under four parallel headings: first, analysis of the topochemical postulate according to which the course of the solid state reaction and the stereochemistry of the photodimer (if any) can be predicted from the configuration and nearest-neighbour geometry of closest monomer molecules in the crystal lattice; secondly, the study of the lOCUS of the reaction, that is the dependence of the course or (dimerization, cis trans isomerization) on crystal texture (dislocation
