In the title compound, C15H20O7, the benzene ring makes dihedral angles of 69.17 (5) and 80.81 (4)° with the two side chains of malonate. The two malonate side chains comprising C/C/O/C atoms are oriented at right angles [86.26 (6)°] with respect to each other. In the crystal structure, the crystal packing is stabilized by weak non-classical intermolecular C—H⋯O hydrogen bonds, which link the molecules into an infinite network.
Substituted malonate, an important organic intermediate, is electrooxidized in methanol in the presence of halogen ions to afford the corresponding halomalonates, see: Okimoto & Takahashi (2002 ▶). For a related structure, see: Liu et al. (2010 ▶).
