配位聚合物（CP）是由金属离子和有机连接分子组装而成。在这里，我们证明，CP可以用作简单和复杂的氧化物合成的前体。首先，我们研究了连接剂溶液的条件，其中CP仅通过混合和搅拌28种金属离子水溶液中的每一种溶液而作为沉淀物获得。通过焙烧沉淀物获得的样品的结晶相的评估显示，CP可以用作21种金属离子的简单氧化物的前体。接下来，我们进行了实验，以制备具有含有等摩尔量的金属离子的AnBnOM组合物的10种复合氧化物的前体。成功地合成了七种复合氧化物。其中三种是喷雾共沉淀法不能合成的复合氧化物。本方法具有与喷雾共沉淀法相当的前体制备能力。由于前驱体合成的时间短得多，本方法应该是有用的平行和自动化实验。
Coordination polymers (CPs) are assembled from metal ions and organic linker molecules. Here, we demonstrate that CPs can be used as precursors for simple and complex oxide synthesis. First, we investigated the conditions for linker solutions in which CP was obtained as precipitate only by mixing and stirring the solutions for each of the 28 metal–ion aqueous solutions. Evaluation of the crystalline phase of the samples obtained by firing the precipitates revealed that CPs could be used as precursors of simple oxides for 21 metal ions. Next, we conducted experiments to prepare precursors of 10 complex oxides with anAnBnOmcomposition containing equimolar amounts of metal ions. Seven complex oxides were successfully synthesized. Three of them were complex oxides that could not be synthesized by the spray coprecipitation method. The present method has a comparable precursor preparation capability to the spray coprecipitation method. Because of the much shorter time for the precursor synthesis, the present method should be useful for parallel and automated experiments.
