title: Three-dimensional hydrogen-bonding supramolecular architecture of 2-(3-pyridinio)-5-(3-pyridyl)-1,3,4-oxadiazole perchlorate.
abstract: In the crystal structure of the title compound, C(12)H(9)N(4)O(+).ClO(4)(-), the protonated cation adopts a cis-I conformation and approximately planar geometry. Each perchlorate anion acts as the acceptor of three C-H...O weak interactions, which, together with N-H...N and C-H...N hydrogen bonds between the protonated cations, extend this structure into a three-dimensional hydrogen-bonded network.
