Synthesis and solid state structure of α,α′-bis(2-phenyl-1,2-carboran-1-yl)lutidine

α,α′-Bis(2-phenyl-1,2-carboran-1-yl)lutidine has been prepared and the solid state structure characterised by X-ray diffraction. The structure reveals weak CH⋯π interactions between molecules, forming a herringbone motif. Surprisingly, the pyridyl nitrogen atoms take part in no long-range interactions.
