A metal-organic compound 2Dioxane {center_dot} 2H{sub 2}O {center_dot} CuCl{sub 2} has been synthesized and structurally characterized by x-ray crystallography. Magnetic susceptibility and zero-field inelastic neutron scattering have also been used to study its magnetic properties. It turns out that this material is a weakly coupled one-dimensional S = 1/2 Heisenberg antiferromagnetic chain system with chain direction along the crystallographic c axis and the nearest-neighbor intrachain exchange constant J = 0.85(4) meV. The next-nearest-neighbor interchain exchange constant J{prime} is also estimated to be 0.05 meV. The observed magnetic excitation spectrum from inelastic neutron scattering is in excellent agreement with numerical calculations based on the Mueller ansatz.
