We report here magnetic studies of Cu-based organometallic monomers 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 {theta}{approx}1 K. The low-temperature magnetization remains linear to {mu}{sub {ital B}H}/{ital k}{sub {ital B}T} {ge} 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.
