An electron paramagnetic resonance (e.p.r.) study at 9.1 and 12.0 GHz on polycrystalline copper(II) benzoate has given the following Spin Hamiltonian parameters for the binuclear molecule: D = 0.3311 ± 0.0006 cm−1, E = 0.0147 ± 0.0003 cm−1, gx = 2.048 ± 0.004, gy = 2.074 ± 0.004, gz = 2.345 ± 0.004. Using the average g value of 2.160 ± 0.004 obtained from e.p.r. and previously published magnetic susceptibility studies, 2J is estimated to be 333 cm−1.
