摘要
Temperature-dependent magnetic susceptibility data for [(C2H5)4N]2[CrII(C2B10H12] have been collected in the range 1.4-80 K. The magnetic data may be fit to the Curie-Weiss law x = C/(T-θ) with g = 2.00 and θ = -1.7 K. Magnetic data for Cs[CrIII(C2B9H11)2] yield g = 1.98 and θ = -1.5 K, in excellent agreement with results from EPR studies. The deviations from the Curie law, as indicated by the θ values, are thought to arise from single-ion effects. © 1979, American Chemical Society. All rights reserved.
