Low-dimensional magnetic materials with spin-12 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, Cu(NCS)2, a one-dimensional coordination polymer which displays low-dimensional quantum magnetism. Magnetic susceptibility, electron paramagnetic resonance (EPR) spectroscopy, 13C magic-angle spinning nuclear magnetic resonance (MASNMR) spectroscopy, and density functional theory (DFT) investigations indicate that Cu(NCS)2 behaves as a two-dimensional array of weakly coupled antiferromagnetic spin chains (J2=133(1) K, α=J1/J2=0.08). Powder neutron-diffraction measurements confirm that Cu(NCS)2 orders as a commensurate antiferromagnet below TN=12 K, with a strongly reduced ordered moment (0.3 μB) due to quantum fluctuations.
