title: Tetra-methyl 5,5'-[4,5-dicyano-1,2-phenyl-enebis(-oxy)]diisophthalate chloro-form monosolvate.
abstract: In the title compound, C(28)H(20)N(2)O(10)·CHCl(3), the phen-oxy rings are inclined to the central phenyl ring at dihedral angles of 84.71 (13) and 80.56 (13)°. In the crystal, pairs of weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules related by an inversion center, forming dimers. There are also C-H⋯π inter-actions present.
