摘要：

Proton transfer occurred during co-crystallization of 1,2-(4-pyridyl) ethane with 2-(4-hydroxyphenylazo) benzoic acid to yield a salt comprising a 1: 2 ratio of 1,2-bis (4-pyridinium) ethane dications and 2-(4-hydroxyphenylazo) benzoate anions. Centrosymmetrically related anions associate by charge-assisted O-H center dot center dot center dot O hydrogen bonds to form 24-membered {center dot center dot center dot OC3N2C4OH}(2) synthons. These are connected into a supramolecular polymer via charge-assisted N-H center dot center dot center dot O hydrogen bonds involving the 1,2-bis(4-pyridinium) ethane dications. The compound crystallizes in the triclinic space group P-1with a = 8.517(4) angstrom, b = 9.110(5) angstrom, c = 10.477(5) angstrom, alpha = 96.850(13)degrees, beta = 94.446(12)degrees, gamma = 104.946(10)degrees and Z = 1 {two anions and a dication}.
