title: Crystal structure of 1-benzyl-3-methyl-1H-imidazolium hexa-fluorido-phosphate.
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.
