title: 4,4'-Dianilino-3,3'-(4-chloro-benzyl-idene)bis-[furan-2(5H)-one].
abstract: In the mol-ecule of the title compound, C(27)H(21)ClN(2)O(4), the dihedral angle between the furan rings is 67.00 (3)°. The chloro-phenyl ring is oriented at dihedral angles of 76.61 (3) and 69.36 (3)° with respect to the furan rings. An intra-molecular N-H⋯O inter-action results in the formation of an eight-membered ring with a twisted conformation. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network, forming R(2) (2)(16) ring motifs. Three weak C-H⋯π inter-actions are also found.
