报告了水、乙酸、乙酰丙酮混合配位重稀土(镝、钬、铒、铥、镥)双核络合物单晶的制备和性质。络合物由一个水分子、一个乙酸根、两个乙酰丙酮根配位到一个中心稀土离子上,稀土离子间通过配位乙酸的氧以氧桥形式相联接,构成两核络合物。镝、钬和铒的络合物属于三斜晶系,一个晶胞里只有一个双核络合物分子;铥和镥的络合物属于正交晶系,一个晶胞里有四个双核络合物分子。这两组晶体结构不同的络合物在红外和拉曼光谱以及X射线衍射等性质上都有明显的差异。
The preparation and properties of binuclear complex single crystals with water, acetic acid and acetylacetone mixed coordination heavy rare earths (dysprosium, holmium, erbium, gallium, gallium) were reported. Complex from a water molecule, an acetate, two acetylacetonate coordination to a central rare earth ions, rare earth ions through the coordination of acetic acid oxygen oxygen bridge form connected to form two nuclear complexes. Dysprosium, holmium and erbium complexes belong to the triclinic system, there is only one binuclear complex molecule in one unit cell; the complexes of 铥 and 属 belong to the orthorhombic system, and there are four binuclear complexes in one unit cell Molecule. The two groups of crystal structures of different complexes in the infrared and Raman spectroscopy and X-ray diffraction and other properties have significant differences.
