等人在LaCl_3-CH_3CONH_2-H_2O三元体系30℃时的研究中得到了一个三元复合物(前文文献[2]),我们对同一体系作了较为仔细的研究之后发现,该复合物的组成并非该作者报导的LaCl_3·5CH_3CONH_2·5H_2O,而是LaCl_3·4CH_3CONH_2·5H_2O。我们还对该复合物进行了初步研究,测定了密度,拍摄了显微照片和X-光粉末衍射图,并计算了d/n值(见前文)。本文作为前文工作的继续,对LaCl_3·4CH_3CONH_2·5H_2O-H_2O二元体系进行了研究。
Et al. Obtained a ternary complex in the study of LaCl_3-CH_3CONH_2-H_2O ternary system at 30 ° C [2]. After careful study of the same system, we found that the composition of the complex Rather than the LaCl_3 · 5CH_3CONH_2 · 5H_2O reported by the authors, LaCl_3 · 4CH_3CONH_2 · 5H_2O is reported. We also conducted a preliminary study of the complex, measured density, photographed micrographs and X-ray powder diffraction patterns, and calculated d / n values (see above). As a continuation of the previous work, the binary system LaCl_3 · 4CH_3CONH_2 · 5H_2O-H_2O has been studied.
