Abstract
The first crystal structure of a 10.10.10 cryptand has been determined, dur ing which an unusual single crystal phase transition was observed; at room temperature, crystals of macrobicycle 1d are monoclinic (alpha) but undergo a first-order topotactic phase change at 207 K to a triclinic (beta) latti ce; full structure determinations at 150 and 210 K were carried out and sho w that both phases adopt the in-in cryptand conformation.
