The electron paramagnetic resonance spectra of Cu 2+ doped in LiH 3 (SeO 3 ) 2 single crystals are studied. The ions reside in different chemically distinct sites. For two of them, the strongest in the EPR spectra, the g and A matrices and the Q tensor are determined. Within the limit of experimental errors, the EPR spectra of one site exhibits an orthorhombic symmetry with a pronounced axial character, while the other site exhibits a monoclinic symmetry. In the last case low symmetry effects such as asymmetries of g and A matrices are evidenced.
