摘要:
以4-咪唑甲醛和4,4’-二氨基二苯醚为原料,分别和过渡金属盐Fe(ClO4)2·6H2O或者Fe(BF4)2·6H2O经原位合成法反应制备得到两个配合物:[Fe2(L)3]X4·solvent(X=ClO4:1, BF4:2),晶体结构表明,配合物1和2均结晶于单斜晶系C2/c空间群,配合物结构为3个配体螯合2个金属的三螺旋,2个铁离子位于八面体配位场环境中,主体结构周围游离着阴离子以及溶剂分子。磁性测试表明两种化合物都具有受阴离子调控的不完全自旋转变行为。
Abstract:
Treatment of Iron(II)salts and 4, 4’-diaminodiphenyl ether, 1H-imidazole-4-carbaldehyde lead to two Fe complexes[Fe2(L)3]X4·solvent(X=ClO4:1, BF4:2), which were structurally characterized by X-ray single crystal diffraction. Complexes 1 and 2 crystallize in the monoclinic C2/c space group. The complexes have a similar triple helicate structure composed of three organic ligands and two Fe(II)ions in an octahedral coordination geometry. Magnetic measurements confirmed that iron(II)complexes exhibit gradual and incomplete spin crossover(SCO)behavior which is found to be influenced by anion.
