4,4'-(Azinodimethylene)dipyridinium bis(tetrafluoroborate) and 4-[(4-pyridylmethylene)hydrazonomethyl]pyridinium perchlorate: two different hydrogen-bonding motifs
Journal article, 2007

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-H...F [in (I)] and conventional N-H...N [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)°.
