Abstract
Low-dimensional magnetic materials with spin- moments can host a range of exotic magnetic phenomena due to the intrinsic importance of quantum fluctuations to their behavior. Here, we report the structure, magnetic structure, and magnetic properties of copper ii thiocyanate, , a one-dimensional coordination polymer which displays low-dimensional quantum magnetism. Magnetic susceptibility, electron paramagnetic resonance spectroscopy, magic-angle spinning nuclear magnetic resonance spectroscopy, and density functional theory investigations indicate that behaves as a two-dimensional array of weakly coupled antiferromagnetic spin chains , . Powder neutron-diffraction measurements confirm that orders as a commensurate antiferromagnet below , with a strongly reduced ordered moment () due to quantum fluctuations.
