Crystal structure of 3,6-dihy­droxy-4,5-di­methyl­benzene-1,2-dicarbaldehyde

The title compound, C(10)H(10)O(4), was synthesized from tetra­methyl-1,4-benzo­quinone. In the crystal, the almost planar mol­ecule (r.m.s. deviation = 0.024 Å) forms intra­molecular hydrogen bonds between the aldehyde and hy­droxy groups and exhibits C (2v) symmetry. This achiral mol­ecule crystallizes in the chiral space group P2(1) with inter­molecular O—H⋯O and C—H⋯O hydrogen bonding and C—H⋯π and C=O⋯π inter­actions stabilizing the crystal packing.
