Abstract

Low-temperature X-ray analyses on several pseudopolymorphs (solvate crystals) revealed that the C1C2 bond length of the highly congested title molecule can adopt quite different values [1.700(6)1.739( 6)]. Such an unusual observation indicates that the ultralong covalent bond is endowed with "expandability," thus the prestrained bond can be elongated or shortened very easily accompanied by only a minute change in energy, which can be compensated by intermolecular perturbation in the crystal.
