将过渡金属离子引入到Lindqvist多氧钒醇(POV-Alxoxate)簇合物中是一种有效的方法来调节这些分子组装的电子性质。在这里，我们报道了一种镓功能化的POV-醇盐簇合物的合成，将异金属功能化簇合物的家族扩展到类金属离子，通过红外光谱、电子吸收光谱和循环伏安对配合物[V5O6(OCH3)(12)GaCl]进行了表征，揭示了3D(10)离子安装后的广泛离域保留。新的反应条件表明，[V_5O_6(OCH_3)(12)GaCl]可以从铁盐前驱体中成功地生成铁的类似物[V_5O_6(OCH_3)(12)GaCl]。然而，尝试安装其他第13族离子，例如In-III，反而产生了环状六钒酸簇合物[Bu4N][V5O6(OCH3)(12)GaCl]。(C)2018爱思唯尔有限公司。保留所有权利。
Incorporating transition metal ions into Lindqvist polyoxovanadate-alkoxide (POV-alkoxide) clusters has been shown to be an effective method for tuning the electronic properties of these molecular assemblies. Herein, we report the synthesis of a gallium-functionalized POV-alkoxide cluster, extending the family of heterometal-functionalized clusters to a metalloid ion, Complex [V5O6(OCH3)(12)GaCl] was characterized by infrared and electronic absorption spectroscopies and cyclic voltammetry, revealing the retention of the extensive delocalization upon installation of the 3d(10) ion. The new reaction conditions developed for[V5O6(OCH3)(12)GaCl] were shown to successfully generate the iron analogue, [V5O6(OCH3)(12)GaCl], from a ferric salt precursor. However, attempts at installing other group 13 ions, e.g. In-III, instead produced the cyclic hexavanadate cluster, [Bu4N][V5O6(OCH3)(12)GaCl]. (C) 2018 Elsevier Ltd. All rights reserved.
