摘要
采用化学合成的方法制备了分子基合金磁体(Ni_xMn_(1-x))_(1.5)[Cr(CN)_6],X-射线分析表明,制备的分子基合金磁体具有面心立方结构,晶格常数随Ni的成分x的增加而减小,红外光谱(IR)分析显示Cr-CN的键的特征随Ni的成分x的变化而改变。
Molecular alloys magnets ( Nix Mn1 x)1.5 [Cr(CN)6 ] were prepared by reacting mixtures of Nitl2 and MnCl2 aqueous solutions with K3Cr(CN)6 aqueous solution. X-ray powder-diffraction patterns for all of the ternary com-plexes were consistent with the fcc structure. The lattice constant decreased successively with increasing x. Infrared spec-tra results show that the character of the bond between the metal (Cr)and CN were successively changed depending on x.
