Popis:	The EPR spectra of single crystals of 63Cu(II) doped N, N'-bis(salicylidene)-o-phenylenediimine Ni(II), (Ni(II)(sal)2 phen), and N, N'-bis(7-methyl salicylidene)-o-phenylenediimine Ni(II), (Ni(II)(7-me sal)2phen) have been studied. The usual doublet spin-Hamiltonian parameters have been found to be: 63Cu(II) doped Ni(II)(sal)2phen; gz = 2.192·0.002,gx = 2.049·0.004,gy = 2.041·0.004,Az = 201.7 × 10−4 cm−1,Ax = 36.4 × 10−4 cm−1, Ay = 31.4 × 10−4 cm−1,AN = 11.3 × 10−4 cm−1,A· = 14.0 × 10−4 cm−1,A·=5.7 × 10−4 cm−1,A· = 7.0 × 10−4 cm−1; 63Cu(II) doped Ni(II)(7-me sal)2 phen;gz = 2.209·0.002,gx = 2.049·0.004, gy = 2.044 · 0.004, Az = 197.4 × 10−4 cm−1, Ax = 28.7 × 10−4 cm−,Ay , = 24.8 × 10−4 cm−1,A· = 10.6 × 10−4 A· = 13.0 × 10−4 cm−1. A comparison of the optical transitions and the values of the magnetic parameters for these two complexes indicate that there is a small tetrahedral distortion present in Cu(II)(7-me sal)2 phen.
