Anisotropic Thermal Expansion in an Anionic Framework Showing Guest-Dependent Phases
Crystalline materials generally show small positive thermal expansion along all three crystallographic axes because of increasing anharmonic vibrational amplitudes between bonded atoms or ions pairs on heating. In very rare cases, structural peculiarities may give rise to negative, anomalously large...
