合成了九个新的含铁希土化合物LnFe(CN)_2(CONH_2)_4。通过元素分析、红外光谱对它们进行了表征。化合物的~(57)Fe穆斯堡尔参数表明,化合物中铁处于三价低自旋志,有从铁向希土的电子转移作用。
Nine new iron-containing rare earth compounds LnFe (CN) _2 (CONH_2) _4 were synthesized. They were characterized by elemental analysis and infrared spectroscopy. The ~ (57) Fe Mössbauer parameters of the compounds show that the iron in the compound is in a trivalent low spin cycle and has an electron transfer from iron to the earth.
