On the crystal structure and low-temperature behaviour of davyne: A single-crystal X-ray and neutron diffraction study

- Single-crystal X-ray and neutron structure refinements of a davyne were performed.
- The disordered configuration of the extraframework population is provided.
- The low-T behavior of davyne was investigated by single-crystal X-ray diffraction.
- The thermo-elastic behavior is described by in situ measurements.
- T-induced structure evolution is described.
