Abstract

New double complex salts [Co(NH3)5Cl][Cu(H2O)(C2O4)2] and [Co(en)3]2[Cu(H2O)(C2O4)2]2[Cu(H2O)2(C2O4)2]·10H2O (en is ethylenediamine) have been prepared and their thermal properties have been studied. The compounds have been characterized by physicochemical methods of analysis (single crystal and powder X-ray diffraction, IR spectroscopy and elemental analysis). It has been found using thermal analysis and powder X-ray diffraction that decomposition of the complex salts leads to formation of metastable CoxCu1–x solid solutions with high mutual solubility of metals. Formation of metastable solid solutions in Co–Cu system has been shown.

氯戊胺-和三(乙二胺)钴(III)草酸盐(II):合成、晶体结构和热性能
制备了新型双络合盐[Co(NH3)5Cl][Cu(H2O)(C2O4)2]和[Co(en)3]2[Cu(H2O)(C2O4)2]2[Cu(H2O)2(C2O4)2]·10H2O (en为乙二胺),并对其热性能进行了研究。用物理化学分析方法(单晶和粉末x射线衍射、红外光谱和元素分析)对化合物进行了表征。通过热分析和粉末x射线衍射发现,配合盐的分解形成了具有高金属互溶性的亚稳CoxCu1-x固溶体。研究了Co-Cu体系中亚稳固溶体的形成。
