摘要
近年来,相继测定了一些过渡金属18-C-6化合物的结构,发现它们的结合方式有着自己的结构特性。作为结构表征的振动光谱,目前还研究得较少。本文合成了(Mn<sub>2</sub>Cl<sub>2</sub>·8H<sub>2</sub>0)·18C6·2Cl(Ⅰ)和Mn(NCS)<sub>2</sub>·4H<sub>2</sub>O·18C6(Ⅱ),测定了4000-100cm<sup>-1</sup>区域的FTIR和激光Raman光谱,讨论了(Ⅱ)的可能结构。
The compounds with molecular formula Mn(NCS)_2·4H_2O·18C6 and (Mn_2Cl_2·8H_2O)·18C6·2Cl were synthesized and their FT-IR, Raman spectra were measured over region of 4000-100 cm^(-1). The vibrational spectra show that in both compounds the Mn^(2+) ion are not coordinated to 18C6 but combined with 18C6 by hydrogen bonds originated from the hydrous water of manganese.In addition, by means of the changes of vibration for crowa ether ring in IR together with that the appearance of a band near 867 cm^(-1), which belongs to the breath vibration of ring, or not, one can predicate that the transition element crown compound with a single nucleus or a long chain structure.
