Abstract

Crystallization of tri-O-[p-halobenzoyl]-myo-inositol 1,3,5-orthoformates from ethyl acetate–petroleum ether solution produced concomitant dimorphs that have different halogen bonding contacts; the kinetic form with C–Br⋯O–C contacts upon heating to 185 °C, converts completely to the thermodynamic form with C–Br⋯O[double bond, length as m-dash]C contacts via crystal-to-crystal first order phase transition.
