Insight into the molecular dynamics of guest cations confined in deformable azido coordination frameworks

Abstract

The molecular dynamics of encapsulated cations within perovskite-like coordination polymers [(CH3)3NH][M(N3)3] (M = Mn, Cd) are investigated, which are well controlled by the confined space of a deformable azido framework. The Mn-based compound provides a rare example that features an unvaried/varied rotational energy barrier during its two different structural phase transitions.
