Popis:	An X-ray crystallographic analysis and dynamic 1H n.m.r. study have shown that the title compound exists in a symmetrical 2,5-twist-boat conformation both in the solid state and in solution; an unusually high barrier for interconversion between the two enantiotopic conformational isomers (32.4 kJ/mol) has been measured.
