Abstract

[Cu^II(chxn)₂I]I (chxn = 1R,2R-diaminocyclohexane) has been synthesized, which is the first report of an iodide-bridged Cu(II) chain structure. This chain compound shows S = 1/2 Heisenberg weak antiferromagnetism (J = -0.3 cm^-1) and magnetic relaxation (τ = 43 ms at 1.8 K) with a Raman process in a static field.
