In the title Ho(III)-erythritol complex, [Ho(NO3)3(C4H10O4)(C2H5OH)], the Ho(III) cation is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. An ethanol mol-ecule further coordinates the Ho(III) cation, completing the irregular O10 coordination geometry. In the crystal, an extensive O-H⋯O hydrogen-bond network links the mol-ecules into a three-dimensional supra-molecular structure.
在标题化合物三硝酸钬(III)-赤藓糖醇配合物[Ho(NO₃)₃(C₄H₁₀O₄)(C₂H₅OH)]中,Ho(III)阳离子由一个三齿赤藓糖醇配体和三个双齿硝酸根阴离子螯合。一个乙醇分子进一步与Ho(III)阳离子配位,形成不规则的O10配位几何构型。在晶体中,广泛的O-H⋯O氢键网络将分子连接成三维超分子结构。
