Crystal structure and fluorescence study of (μ-N-[(3,5-dimethyl-1H-pyrrol-2-yl)methylidene]-N-{4-[(3,5-dimethyl-1H-pyrrol-2-yl)methylideneazaniumyl]phenyl}azanium)bis[difluoridoboron(IV)]

The title molecule, C20H20B2F4N4, assumes a planar conformation with all atoms apart from the F atoms lying on the symmetry plane. Each boron atom is four-coordinated by two fluorine atoms, a pyrrole N atom and an imine N atom. Both imine CH=N groups adopt a trans conformation. In the crystal, the molecules self-assemble into a pillar structure through C—H...F hydrogen bonds and π–π interactions. The UV–vis spectrum and fluorescence spectra of the title compound are also reported.
