3,9-Bis(2,4-dichloro-phen-yl)-2,4,8,10-tetra-oxaspiro-[5.5]undeca-ne.

ABSTRACT: In the title compound, C(19)H(16)Cl(4)O(4), the two halves of the mol-ecule 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, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis.
