CH₃CN: X-ray structural investigation of a unique single crystal. phase transition and crystal structure

R. Enjalbert and J. Galy

Abstract: The phase transition from the low- ( [beta] ) to the high-temperature ( [alpha] ) form of acetonitrile, CH₃CN, has been directly observed and studied on a unique single crystal. Both the [beta] and [alpha] structures have been determined at temperatures close to the transition temperature (206 K and 201 K), taking advantage of the hysteresis. A single crystal of the [beta] form was obtained for the first time.

Keywords: solid-solid phase transition; single-crystal form; acetonitrile.
