The spin Hamiltonian parameters (g-factors and hyperfine structure constants) and defect structure of tetragonal Cu2+ ion in SrCl2 are theoretically investigated, using the high-order perturbation formulas for 3d 9 ions in tetragonally elongated octahedra. In these formulas, the contributions to the spin Hamiltonian from the ligand orbital and spin-orbit coupling interactions are considered with respect to strong covalency. Based on the studies, the impurity Cu2+ is found to be located at a distance of about 0.42 Å from the nearest chlorine plane. The signs of the hyperfine structure constants A|| and A are suggested. The theoretical spin Hamiltonian parameters show good agreement with the experimental values. The results are discussed.
