摘 要:在非水溶剂中合成了苯并-15-冠-5与碘化钾、硫氰化钾及苦味酸钾形成的三种新型固体配合物,并进行了有关物理、化学性质表征.结果表明,钾(Ⅰ)离子不仅易与苯并-15-冠-5形成常见的1:2夹心式配合物,而且还能生成稳定的1:1型固体配合物.n this paper, three novel solid complexes of benzo-15-crown-5 with potassium iodine,thiocyanate and picrate respectively, having compositions of K(B15CS)X(X=NCS-, Pic-) and K(B15C5)I·2CO(CH3)2, have been synthesized in nonaqueous solvent, and characterized by clemental analyses, infrared spectra, X-ray powder diffraction analyses, molar conductance measurements. In addition, some differences between two types of complexes (K+: B15CS=1: 1 or 1: 2) are reasonably discussed. If crown to salt ratio is one to one or larger than one to one, 1: 2 'sandwich structure' complexes are isolated, whereas 1:1 complexes form if this ratio is smaller than one to one. The structure of 1: 1 type complexes isolated are not the same as that of the corresponding 1: 2 type complexes.
