The title compound (C₁₄H₁₀N₂O₂Cl₂) crystallizes in the monoclinic space group P2₁/a with a=10.042(1) Å, b=10.317(1) Å, c=13.877(2) Å, β=97.36(2)°, V=1425.8(3) Å³, Z=4, D_x=1.44 g.cm^-3. The structure was solved by direct methods and refined by full-matrix least-squares method (R=0.0457). The title molecule consists of 3,4-dichlorophenylamino and 2-phenyl-1,2-ethanedione-1-oxime groups. The intermolecular O-H…N and N-H…O hydrogen bonds [O…N 2.760(6) and 3.087(5) Å] are highly effective in forming the polymeric chains. The oxime group has an E configuration.
