 Title    X-Ray Structure4]non-2-ene  
 Abstract    of 6(is)-[2(Z)-(Hydroxyimino)-2-phenylethyIidene]-7,7,8,8,9,9-hexamethyl-3-phenyl-l,2-oxazaspiro[4. The X-ray crystallographic structure of the title compound, a product of a 1,3-dipolar cy­ cloaddition reaction of benzonitrile oxide to 3,3,4,4,5,5-hexamethyl-l,2-bis(methylene)cyclo-pentane, has been determined. Colourless plates crystallize in the orthorhombic space group Pbca with cell dimensions a = 13.698(2), b = 11.836(2), c = 29.157(4) A, V= 4727.2(1.2)A3, Z = 8, 3736 reflections, final R(F) = 0.063 and wR(F2) = 0.166. The crystals are racemic, the molecules of opposite chirality form centrosymmetric dimers via intermolecular hydro­ gen bonds O-H -N between their oxime groups. The molecules are highly strained and the geometrical consequences of the steric strain are discussed.
