title: Hydrogen-bonded 1:1 adduct of 1,1'-(p-phenylene)dipyridin-4(1H)-one with terephthalic acid.
abstract: Cocrystallization of 1,1'-(p-phenylene)dipyridin-4(1H)-one (4,4'-dpy) and terephthalic acid (tpa) affords the hydrogen-bonded 1:1 title complex, C16H12N2O2.C8H6O4. Both molecules are symmetrically disposed about independent symmetry centers. Strong O-H...O hydrogen bonds between tpa carboxyl groups and 4,4'-dpy carbonyl groups produce one-dimensional zigzag infinite chains. Each chain is linked to four surrounding chains via weak C-H...O interactions, resulting in a three-dimensional molecular framework.
