Pyridine-4-carbaldehyde–fumaric acid (2/1)

In the title co-crystal, 2C(6)H(5)NO·C(4)H(4)O(4), two crystallographically different hydrogen-bonded trimers are formed, one in which the components occupy general positions, and one generated by an inversion centre. This results in the uncommon situation of Z = 3 for a triclinic crystal. In the fo...

Sumario:In the title co-crystal, 2C(6)H(5)NO·C(4)H(4)O(4), two crystallographically different hydrogen-bonded trimers are formed, one in which the components occupy general positions, and one generated by an inversion centre. This results in the uncommon situation of Z = 3 for a triclinic crystal. In the formula units, mol­ecules are linked by O—H⋯N hydrogen bonds.
