Abstract

In the title salt, C11H13N2 (+)·PF6 (-), the dihedral angle between the planes of the imidazole and benzene rings is 84.72 (4)°. In the crystal, C-H⋯F inter-actions connect the cation and anion pairs into a three-dimensional network. Weak π-π inter-actions are observed between the imidazolium ring and the aromatic benzene ring of an adjacent mol-ecule with C⋯C and C⋯N distances ranging from 3.3714 (16) to 3.4389 (15) Å.

Keywords: crystal structure; hexa­fluorido­phosphate; hydrogen bonding; imidazolium; π–π inter­actions.
