含有草酸盐配体的均和杂金属可溶性配位聚合物和由其获得尖晶石的方法
摘要：
本发明涉及含有草酸盐配体的均和杂金属可溶性配位聚合物以及由其获得尖晶石的方法。含有至少一种草酸盐配体的均或杂金属配位聚合物的特征在于，还含有至少一种有机分子，所述有机分子可以通过形成超分子相互作用而稳定伸长的金属配合物结构，使得此聚合物基本上是水溶性的，并且不溶于有机溶剂。所述聚合物在处于固态时，可以在热氧化处理后生成尖晶石型金属氧化物或其它混合氧化物，包括以下步骤：制备金属配合物和金属盐的醇溶液，所述金属配合物包含至少一种草酸盐配体；使用穴状配体型分子，通过形成可溶于水并且不溶于有机溶剂的配位聚合物，使该金属配合物和该金属盐沉淀；分离在前一步骤中获得的沉淀物并且将其在至少350℃的温度、在氧化气氛下加热，直至形成尖晶石或混合氧化物。
摘要（英）：

The invention relates to homo and heterometallic soluble coordination polymers containing an oxalate ligand and to a method for obtaining spinels from same. The homo and heterometallic coordination polymers, which contain at least one oxalate ligand, are characterised in that they also contain at least one organic molecule capable of stabilising expanded metal complex structures through the formation of supramolecular interactions such that the polymer is substantially soluble in water and insoluble in organic solvents. Said polymers, when in the solid state, can generate spinel-type metal oxides or other mixed oxides following a thermal oxidation treatment including steps comprising: the preparation of an alcoholic solution of a metal complex containing at least one oxalate ligand and a metal salt, the precipitation of the metal complex and the metal salt with a cryptand-type molecule through the formation of a coordination polymer that is soluble in water and insoluble in organic solvents, the separation of the precipitate obtained in the previous step, and the heating of same in an oxidant atmosphere to a temperature of at least 350 DEG C until the spinel or mixed oxide has formed.
