ABSTRACT: The macrocycle of the title compound, C(36)H(24)N(4)O(3)S·2CHCl(3), contains a rigid framework with the nitro-gen and oxygen heteroatoms pointing in towards the center of the macrocyclic cavity. The macrocycle is essentially planar (r.m.s. deviation = 0.027 Å) except for the thio-phene ring. The dihedral angle between the thio-phene ring plane and the mean plane of the central macrocyclic core including all atoms except sulfur is 21.6 (1)°. Four intra-molecular hydrogen bonds occur: two are between the amide hydrogen atoms and the Schiff base nitro-gen atoms, while the others are between the amide hydrogen atoms and the sulfur atom of the thio-phene. The two solvate chloro-form mol-ecules are bound to the carbonyl oxygen atoms of the ligand by weak C-H⋯O hydrogen bonding. In addition, the
