Structure and energetics of trivalent metal halides [PDF]
, 1999 Metal trihalide (MX3) systems represent a stern challenge in terms of constructing transferable potential models. Starting from a previously published set of potentials, 'extended' ionic models are developed which, at the outset, include only anion ...

BHAS Coupling of Aryl Halides to Arenes Facilitated by Nickel Complexes [PDF]
, 2023 Aryl halides are efficiently coupled to benzene using air-stable Ni(COD)(DQ) (COD = 1,5-cyclooctadiene, DQ = duroquinone) and KOtBu, without additional ligands. Mechanistic evidence suggests that Ni(COD)(DQ) and KOtBu act as an initiation source, forming

Phase-Transferable Force Field for Alkali Halides [PDF]
, 2018 A longstanding goal of computational chemistry is to predict the state of materials in all phases with a single model. This is particularly relevant for materials that are difficult or dangerous to handle or compounds that have not yet been created ...
