Abstract

The title compound has been fully characterised by ¹H and ¹³C NMR spectroscopy which reveals (E) to (Z) isomerisation upon dissolution. In the solid state, X-ray diffraction shows exclusively the (E)-isomer with two geometrically near-identical independent molecules each with the outer rings tilted with respect to the central ring.
