title: Crystal structure of 2-cyano-1-methyl-pyridinium tetra-fluoro-borate.
abstract: The asymmetric unit of the title salt, C7H7N2 (+)·BF4 (-), comprises two independent but nearly identical formula units. The solid-state structure comprises corrugated layers of cations and anions, formed by C-H⋯F hydrogen bonding, that are approximately parallel to (010). Further C-H⋯F hydrogen bonding consolidates the three-dimensional architecture. The sample was refined as a two-component non-merohedral twin.
