In the title Er(III)-erythritol complex, [Er(NO3)3(C2H5OH)(C4H10O4)], the Er(III) cation is chelated by one erythritol mol-ecule, three nitrate anions and an ethanol mol-ecule, completing an irregular ErO10 coordination geometry. The Er-O bond lengths are in the range 2.348 (3)-2.583 (3) Å. In the crystal, extensive O-H⋯O hydrogen bonding links the mol-ecules into a three-dimensional supra-molecular structure.
在标题化合物铒(III)-赤藓糖醇配合物[Er(NO₃)₃(C₂H₅OH)(C₄H₁₀O₄)]中,Er(III)阳离子被一个赤藓糖醇分子、三个硝酸根阴离子和一个乙醇分子螯合,形成了一个不规则的ErO₁₀配位几何构型。Er-O键长在2.348(3)-2.583(3) Å范围内。在晶体中,广泛的O-H⋯O氢键将分子连接成三维超分子结构。
