A homochiral helical coordination polymer of copper( ii) has been synthesized using achiral precursors. End-to-end cyanate bridges mediate ferromagnetic exchange interactions among copper( ii) centres.
A homochiral helical coordination polymer of copper( ii) has been synthesized using achiral precursors via spontaneous symmetry breaking and has been confirmed by single crystal X-ray diffraction and solid-state CD spectroscopy. The variable temperature magnetic measurements indicate the presence of weak ferromagnetic exchange interactions mediated by end-to-end cyanate bridges ( J = +0.12 cm −1).
