The title compound, (Hdipya)(H(3)pyr), where Hdipya is protonated 2,2'-dipyridilamine and H(3)pyr is the monoanion of pyromellitic acid (H(4)pyr), was obtained from a reaction mixture containing Zn(II) ions, dipya, Na(4)pyr (in the mole ratio 2:2:1) and HNO3. The products (micro- and single-crystalline) were characterized by X-ray structure determination, FT-IR spectroscopy and TG/DSC analysis. The most striking structural feature of (Hdipya)(H(3)pyr) are short inter- and extremely short intramolecular hydrogen bonds. These bonds mutually connect cations and anions making thin layers parallel to the crystallographic (223) plane. In addition, quite unusual, linear proton-bound polymeric {H(H(2)pyr)(-)}(n) were identified in the structure. The results of crystal structure determination are compared with FT-IR and TG/DSC data. The low position of the nu(as)(COO) vibration at 1660 cm(-1) is in accordance with strong hydrogen bonding. This value could be used as a measure of the C=O bond or...der, which was calculated to be 1.81.
