Crystal structure and Hirshfeld surface analysis of 2,5-di­bromo­terephthalic acid ethyl­ene glycol monosolvate

The title compound, C(8)H(4)Br(2)O(4)·C(2)H(6)O(2), crystallizes with one-half of a 2,5-di­bromo­terephthalic acid (H(2)Br(2)tp) mol­ecule and one-half of an ethyl­ene glycol (EG) mol­ecule in the the asymmetric unit. The whole mol­ecules are generated by application of inversion symmetry. The H(2)Br(2)tp mol­ecule is not planar, with the di­bromo­benzene ring system inclined by a dihedral angle of 18.62 (3)° to the carb­oxy­lic group. In the crystal, the H(2)Br(2)tp and EG mol­ecules are linked into sheets propagating parallel to ([Image: see text]01) through O—H⋯O hydrogen bonds, thereby forming R (4) (4) (12) and R (4) (4) (28) graph-set motifs. Br⋯O and weak π–π stacking inter­actions are also observed. Hirshfeld surface analysis was used to confirm the existence of these inter­actions.
