In the heteromolecular title compound, C₁₅H₁₀O₅·C₁₀H₈N₂, the two components are linked by O—H⋯N hydrogen bonds to form four-component ring supramolecular assemblies. These are further interconnected with neighbouring molecules by weak intermolecular C—H⋯π interactions and C—H⋯O hydrogen bonds to generate a three-dimensional network.

Comment top

The asymmetric unit consists of one 4,4'-bipyridine molecule and one 4-(2-carboxylbenzoyl)benzoic acid molecule (Fig. 1). The two components are linked by O—H···N hydrogen bonds to form four-component ring supramolecular adducts (Tab. 1 & Fig. 2). The four-component ring supramolecular adducts interact with neigboring molecules via weak intermolecular C—H···π interactions and C—H···O hydrogen bonds (Tab. 1). The C—H···π interactions link the four-component ring supramolecular adducts into two-dimensional layers (Fig. 3), which are further connected by weak intermolecular C—H···O hydrogen bonds to generate a three-dimensional supramolecular structure (Fig. 4).

Experimental top

4,4'-bipyridine (0.1 mmol), 4-(2-carboxylbenzoyl)benzoic acid (0.1 mmol), and NaOH (0.2 mmol) were added to a H₂O solution (15 ml) in a Teflon-lined stainless steel reactor. The mixture was heated at 473 K for 3 d, and then slowly cooled down to room temperature. Colorless crystals of the title compound were obtained.
