摘要：

A mixed-halide bis(benzylammonium)tetrahalogenochromate(II), (C6H5CH2NH3)2CrBr3.3I0.7, has been synthesized and characterized. The compound crystallizes in the layered K2NiF4 perovskite structure. It orders ferromagnetically at T(c) = 51 K, one of the highest critical (Curie) temperatures shown by magnetic insulators. A hysteresis loop typical of a soft ferromagnet has been obtained. At T = 6 K, the remnant magnetization is 4.2 x 10(3) cm3 mol-1 G and the coercive field is 130 G.
