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, C(20)H(20)B(2)F(4)N(4), 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 cry...

description The title mol­ecule, C(20)H(20)B(2)F(4)N(4), 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.
