Dimethyl 4,5-dichlorobenzene-1,2-dicarboxyl­ate

In the title compound, C(10)H(8)Cl(2)O(4), the two Cl atoms and one of the meth-oxy-carbonyl groups are almost coplanar [maxi-mum derivation = 0.035 (2) Å] with the benzene plane, and the other meth-oxy-carbonyl group exhibits an almost orthogonal disposition relative to the benzene plane, with a dihedral angle of 84.82 (3)° between the planes. In the crystal, the molecules are connected into a...
