Solid-state structure of a tetrazole-substituted ferrocenium salt with weak intermolecular C–H⋯N hydrogen bonds

A perchlorate salt of ferrocenylphenyltetrazole has been prepared and characterized crystallographically. In the crystal, tape-like one-dimensional molecular arrangements are formed by weak CH⋯N intermolecular hydrogen bonds between the tetrazole moieties (H⋯N distance: 2.49 Å). A layer-like structure was formed, composed of neutral layers of phenyltetrazole moieties and ionic layers of ferrocenium moieties and anions.
