title: Crystal structure of bis-(4-meth-oxy-phenyl) malonate.
abstract: The complete mol-ecule of the title compound, C17H16O6, is generated by crystallographic twofold symmetry, with the central methyl-ene C atom lying on the rotation axis. The carbonyl O atom is disordered over two adjacent positions in a 0.63 (3):0.37 (3) ratio and the dihedral angle between the benzene rings in the two halves of the mol-ecule is 79.31 (12)°. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds, generating (110) sheets. Very weak intra-sheet C-H⋯π inter-actions are also observed.
