Abstract
We report here magnetic studies of Cu‐based organometallicmonomers and polymers.Magnetic susceptibility measurements at high temperature, on monomers having different side groups, show antiferromagnetic Curie–Weiss behavior consistent with a single spin‐1/2 per Cu atom and an antiferromagnetic Curie–Weiss temperature θ≊1 K. The low‐temperature magnetization remains linear to μ BH /k BT ≥ 1, suggestive of 1D antiferromagnetic Heisenberg interactions. A sharp decrease in the effective spin per Cu atom is observed in the polymerized organometallic system, with the number of spins decreasing with the degree of polymerization.This publication has 3 references indexed in Scilit:
