Deskripsi
In the title compound, C19H16Cl4O4, the two halves of the molecule are related by a crystallographic twofold rotation axis passing through the central spiro-C atom. The two non-planar six-membered heterocycles both adopt chair conformations, and the dihedral angle between the two benzene rings is 76.6 (1)°. In the crystal structure, intermolecular C—H...O hydrogen bonds link the molecules into chains along the c axis.
