The complex oxides Li_{1 + x}Ni_{1 / 3}Co_{1 / 3}Mn_{1 / 3}O₂ were obtained by solid state method. The conclusion about influence of lithium concentration on Ni²⁺ and Ni³⁺ ions ratio in Li_{1 + x}Ni_{1 / 3}Co_{1 / 3}Mn_{1 / 3}O₂ is made. Monotonous decrease of g-factor value identified by EPR method testifies the intensification of local exchange interactions with temperature descent. That is in agreement with magnetic susceptibility data indicating the antiferromagnetic ordering at T=4 K.
