4,4'-(Azinodimethylene)dipyridinium bis(tetrafluoroborate) and 4-[(4-pyridylmethylene)hydrazonomethyl]pyridinium perchlorate: two different hydrogen-bonding motifs

M. Ghazzali, V. Langer, L. Öhrström and M. Abu-Youssef

Abstract: In the crystal structures of the title compounds, C₁₂H₁₂N₄²⁺·2BF₄^-, (I), and C₁₂H₁₁N₄⁺·ClO₄^-, (II), respectively, infinite two- and one-dimensional architectures are built up via N-HF [in (I)] and conventional N-HN [in (II)] hydrogen bonding. The N-N single bond in (I) lies on a crystallographic centre of symmetry; as a result, the two pyridinium rings are parallel. In (II), the pyridinium and pyridyl ring planes are inclined with a dihedral angle of 14.45 (3)°.

Formula: C₁₂H₁₂N₄²⁺·2BF₄^- and C₁₂H₁₁N₄⁺·ClO₄^-
