The results of electron spin resonance studies on Cu 2+ doped in potassium hydrogen maleate single crystals at 300 K are presented. The spin Hamiltonian parameters evaluated indicate a square planar environment for Cu 2+ ion in this lattice. From the crystal structure data and the direction cosines of the principal axes of the g tensor, it is concluded that the Cu 2+ ion enters the lattice in an interstitial position. Charge compensation is achieved by the release of protons. Using the optical absorption and ESR data, bonding parameters and orbital reduction factors are also evaluated.
