| 摘要: 继苯甲酰羟胺—钨酰螯合物WO2(C7H6O2N)2的晶体结构测定后,本文报导了整合物MoO2(C7H6O2N)2·C6H13OH的结构和特性,并初步提出了酰羟胺类试剂用于钨钼分离的可能性。苯甲酰羟胺—钼酰螯合物的分子及晶体结构已由四园衍射仪测定,晶体属空间群C2h5—P21/c,晶胞参数a=9.142(1),b=21.591(3),c=11.662(3)Å,β=90.31(1)°,Z=4,最终吻合因子R=0.079.虽然结构中结合的已醇分子无法定位,但它与螯合物分子间强烈的氢键键合作用,则是十分明显的,这很可能是影响苯甲酰羟胺对钨钼分离效果的重要因素之一。 |

| Abstract: To continue the studies on the structure of tungstyl-bisbenzohydroxamate chelate compound, we report herewith the characters and the structure of corresponding molybdenum chelate compound MoO2(C7H6O2N)2·C6H13OH, and preliminarily put forward the possibility about using such kind of benzohydroxamates in the separation of tungsten and molybdenum.The compound crystallized in the space group P21/c with a = 9.142(1), b = 21.591(3),c=11.662(3)Å, β= 90.31(1)° and Z=4. The structure was solved by direct method and refined by full matrix least squares with final R = 0.079 for 4239 observed reflections.In contrast to the correspondent of tungsten, the chelate molecule was hydrogen-bonded to the solvent molecule C6H13OH in the structure, that was why the benzohydroxamate could be used in the separation of tungsten from molybdenum. |
