Crystal structure of racemic trans-1a,7b-dihydro-oxireno[a]naphthalene-3-spiro-2′-oxiran-2(3H)-one
Abstract
The title compound crystallizes in the orthorhombic space group Pbca with cell dimensions a= 16·35, b= 12·39, c= 8·44 Å, Z= 8. The structure was solved from photographic data by the symbolic addition method and refined by a full-matrix least-squares procedure with unit weights to R 0·138 for 312 observed reflections.
