In-plane pyridinium cation reorientation in bis-thiourea chloride, bromide and iodide: quasielastic neutron scattering combined with molecular dynamics simulations

Orientational ordering of guest induced structural phase transition coupled with switchable dielectric properties in a host–guest crystal: bis(thiourea) thiazolium chloride

A host–guest crystal: (thiazolium)[(thiourea)₂Cl] undergoes order-disorder structural phase transition at 213.7 K, accompanied by distinct switchable dielectric responses.
