Synthesis, structure and dispersion interactions in bis(1,8-naphthalendiyl)distibine

Abstract

Naph₂Sb₂1shows intermolecular interactions in the solid state. Quantum chemical calculations of1and the lighter (P, As) and heavier (Bi) congeners showed that intermolecular E⋯E interactions (E = P, As, Sb, Bi) are dispersion dominated, while E⋯π interactions additionally contained a significant electrostatic contribution.
