Abstract
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 hy-droxy isophthalate-based ester and that of the benzo-nitrile moiety. The mol-ecule is bent at the ether linkage, with a Car-yl-O-Car-yl bond angle of 116.74 (11)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and other weak inter-actions forming a supra-molecular framework. A Hirshfeld surface analysis was performed to generate two-dimensional fingerprint plots, which reveal the type of inter-actions occurring in the vicinity of the mol-ecule.

Summary
5-Hydroxyisophthalic acid and its derivatives have been used in the synthesis of several organic ligands. This type of ligand has an isophthalate moiety, which has oxygen-rich carbon chains that are sufficiently reactive to incorporate functionality, followed by conjugation with biomolecular compounds (Calderon et al, 2010; Khandare et al, 2012). Carboxylatecontaining ligands have been used for the synthesis of coordination polymers because of their flexible nature. The flexibility of the ligand and hardness of metal ions improve the stability of coordination polymers (Ahmad et al, 2012). Several types of framework have been obtained, such as metal complexes, clusters, and metal–organic frameworks by linking of the flexible organic linker and metal ion, leading to interesting magnetic properties (Cheon & Suh, 2009; Wang et al, 2009).
