Single crystal of the [CuCl(C6H9N3O3)2 o H2O}2C12 was studied by EPR in 9.4 GHz at room temperature. The components of the g tensor were found to be gc* = 2.241, 0j = 2.094 and ga = 2.062. Since the local symmetry at the cupric ion site is no lower than rhombic, the EPR results were interpreted in terms of the theory for axial symmetry (4 + 1). A consistent explanation of the EPR and optical data is discussed. A comparison of experimental and theoretical resonance line widths suggests that the magnetic system is zero dimensional and the dominant superexchange interaction involves next-nearest neighbour Cu(II) ions.
