Summary Magnetic susceptibility data have been collected in the temperature range 1.8 to 290 K for the di-μ-hydroxo-bridged bimetallic chromium complex di-μ-hydroxo-bis{bis-[(S)alaninato]chromium(III)} trihydrate. The magnetic susceptibility data reflect antiferromagnetic exchange coupling interactions and may be fitted assuming bilinear and biquadratic exchange of the form −2JS1·S2−j(S1·S2)2 using the Van Vleck equation. The best fit of the experimental data yields J=−6.45 cm−1, j=0.65 cm−1, and g=1.98. The magnetic parameters are discussed in terms of the structure of the compound and the correlation between the exchange coupling constant and structural features.
