摘要

合成了分子式为{[CoSr(2,3-pdc)2(H2O)5]·3H2O}n(1)的异金属单源前驱体,并通过元素分析、红外光谱、热分析(TGA)和单晶x射线衍射对其进行了研究。化合物1在三斜空间群P−1中结晶,具有自组织的二维聚合物结构。通过粉末x射线衍射可以确定,1的热分解会生成缺氧型钙钛矿SrCoO2.52。

Heteronuclear (Co-Sr) 2,3-pyridinedicarboxylate complex as precursor to the oxygen-deficient perovskite SrCoO2.52
The heterometallic, single-source precursor with formula {[CoSr(2,3-pdc)2(H2O)5]·3H2O}n (1), has been synthesized and investigated by elemental analysis, IR-spectroscopy, thermal analysis (TGA) and single crystal X-ray diffraction. The compound 1 crystallizes in the triclinic space group P−1 and is self-organized in a polymeric structure of 2D dimension. Thermal decomposition of 1 leads to the formation of oxygen-deficient perovskite SrCoO2.52, as is determined by powder X-ray diffraction.
