The magnetic susceptibility behavior of the mixed-metal molecular-based compounds NBu 4 Fe(II)[Fe(III) x Cr(III) 1 − x (ox) 3 ] has been investigated in the temperature range 5–290 K. The compounds exhibit a crossover from ferromagnetic ordering for NBu 4 Fe(II)[Cr(III)(ox) 3 ] to ferrimagnetic ordering for NBu 4 Fe(II)[Fe(III)(ox) 3 ] as a function of concentration. The increasing substitution of Cr(III) ions by Fe(III) ions showed gradual increases in T N and in the value of the Curie-Weiss constant. The compounds with x > 0.4 have been found to exhibit a spin-glass-like behavior in the temperature region below the magnetic transition temperature. The coexistence of a disordered structure and competition between the ferromagnetic and ferrimagnetic interactions could lead to the observed spin-glass-like behavior in these compounds.
