Spin susceptibility χ obtained by electron spin resonance in quasi-one-dimensional halogen-bridged mixed metal complexes Ni1-xPdx(cyclohexandiamine)2Br3 (0 < x < 1) shows a crossover from Curie-like to weakly temperature-dependent behaviors above around 200 K. The values of χ show a clear enhancement from the linear summation of susceptibilities of Ni and Pd fractions of pure cases, without enhancement of Curie-spin concentration, providing strong evidence for the conversion of nonmagnetic Pd2+ - Pd4+ states into magnetic Pd3+ states in mixed metal chains.
