Description

一种钒酸—铬钼酸混合簇多酸化合物结构及制备方法
所属技术领域
本发明属于无机多金属氧酸盐化学技术领域,涉及同多钒酸—杂多铬钼酸簇混合构筑的多酸化合物的合成,更具体的说是化合物K(H2O)6[H2N(CH2CH2)2O]6[CrMo6O24H6][V10O28H2]·5H2O的制备方法及结构。
背景技术
多金属氧酸盐,也称为金属氧簇化合物(或多酸),是无机晶体材料的一个重要分支,其具有多样化的结构特征和纳米尺寸的体积等特点,表现出独特的光、电、磁性和表面活性等性能,在催化、传感器、吸附、离子交换、离子电导、磁通道材料和非线性光学材料等领域有许多应用前景[1-3]。近年来,随着多酸化学及配位聚合物晶体工程的发展以及合成、表征技术的提高,化学家们开始通过自组装和晶体工程的方法,将多酸化合物结构基团有序地连接起来,构筑成基于金属氧簇的超分子化合物。这类超分子化合物具有丰富的几何构型,在主客体化学,择形催化,吸附,医药以及磁性、荧光和导电材料等领域具有潜在的应用前景。
迄今为止,已有大量以新多酸簇构筑的结构新颖的化合物被报道。但绝大多数化合物都是由同种多酸建筑块构成的,只是展现出单一多酸的功能特性。合成混合多酸建筑块构筑的超分子化合物,在同一化合物中同时具备多种多酸功能特性,这些化合物必将在氧化性、催化活性、光致变色、电致变色、导电性、磁性等方面展示出更优良的特性[4-23]。
本文合成了同多钒酸—杂多铬钼酸簇混合构筑的多酸化合物K(H2O)6[H2N(CH2CH2)2O]6[CrMo6O24H6][V10O28H2]·5H2O,通过元素分析,红外光谱和X-衍射单晶结构对该化合物进行了表征。该化合物组成明确,具有潜在的药物价值。
