N,N′-Bis­(pyridin-4-ylmethyl)succinamide–terephthalic acid (1/1)

Alternate mol­ecules of N,N′-bis­(pyridin-4-ylmethyl)succinamide and terephthalic acid, each of which is located about a centre of inversion, are linked by strong O—H...N hydrogen bonds to form strands in the title compound, C₁₆H₁₈N₄O₂·C₈H₆O₄. In addition, strong N—H...O hydrogen bonds between the N,N′-bis­(pyridin-4-ylmeth­yl)succinamide mol­ecules of adjacent strands link the latter to form sheets.
