چکیده
The title compound, C(14)H(13)Cl(2)NO(3), was obtained as the product of an attempted synthesis of herbicidally active compounds containing oxime ether and cyclo-hexenone groups. In the crystal structure, the mol-ecule adopts an endocyclic enol tautomeric form and the cyclo-hexene ring adopts a distorted envelope form. The oxime ether group has an E configuration, with the meth-oxy group anti to the ortho-chloro substitutent. Intra-molecular O-H⋯O and inter-molecular C-H⋯O hydrogen bonds are found in the crystal structure.

The furan ring and the five-membered fluorene unit in the title compound, C(26)H(22)Cl(2)O(4), adopt envelope conformations. Inter-molecular C-H⋯O inter-actions between symmetry-related mol-ecules involving two C-H groups and an O atom as a bifurcated acceptor generate centrosymmetric hydrogen-bonded dimers with cyclic R(2) (2)(16) and R(2) (2)(8) ring motifs. A short C-H⋯Cl intramolecular cont...
