Tracking anharmonic oscillations in the structure of β-1,3-diacetylpyrene
A recently discovered β polymorph of 1,3-diacetylpyrene has turned out to be a prominent negative thermal expansion material, with a linear thermal expansion coefficient of −199 (6) MK−1 at room temperature. Its unique properties can be linked to anharmonic oscillations in the crystal structure that...
