Positive thermal expansion facilitates the formation of argentophilic forces following an order–disorder phase transition

Abstract

Argentophilic forces are formed in a coordination complex based on silver(I) trifluoromethanesulfonate and 4-stilbazole as a ligand. The forces are absent at low temperature and form as a result of an order–disorder phase transition that occurs upon heating. Colossal positive thermal expansion also precedes the phase transition.
