Tetra-methyl 5,5'-[4,5-dicyano-1,2-phenyl-enebis(-oxy)]diisophthalate chloro-form monosolvate

Crystal structure and Hirshfeld surface analysis of diethyl 5-(2-cyano-phen-oxy)isophthalate

The title compound is non-planar, subtending a dihedral angle of 82.38 (4)° between the plane of hy­droxy isophthalate-based ester and that of the benzo­nitrile moiety. The mol­ecule is bent at the ether linkage, with a C_ar­yl—O—C_ar­yl bond angle of 116.74 (11)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds and other weak inter­actions forming a supra­molecular framework.

The title compound, C₁₉H₁₇NO₅, obtained by ether bond formation between the reagents, crystallizes in the monoclinic space group P2₁/c. The compound is non-planar, subtending a dihedral angle of 82.38 (4)° between the plane of hy­droxy isophthalate-based ester and that of the benzo­nitrile moiety. The mol­ecule is bent at the ether linkage, with a C_ar­yl—O—C_ar­yl bond angle of 116.74 (11)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds and other weak inter­actions forming a supra­molecular framework. A Hirshfeld surface analysis was performed to generate two-dimensional fingerprint plots, which reveal the type of inter­actions occurring in the vicinity of the mol­ecule.
