title: 3-(4-Methoxy-phen-yl)pent-2-ene-1,5-dioic acid.
abstract: In the title compound, C(12)H(12)O(5), mol-ecules are linked into anti-parallel hydrogen-bonded sheets through inversion dimers generated via two O-H⋯O hydrogen bonds. Using the R(2) (2)(8) motif as a building block, hydrogen-bonded chains of a C(2) (2)(8) superstructure are then generated.
