A europium(III) coordination compound based on thio-phene-acrylic acid (Htpa), tri-aqua-tris-[3-(thio-phen-2-yl)prop-2-enoato-κ ,']europium(III)-3-(thio-phen-2-yl)prop-2-enoic acid (1/3), [Eu(CHOS)(HO)]·3CHOS or [Eu(tpa)(HO)]·3(Htpa) (), where tpa is the conjugate base of Htpa, has been synthesized and structurally characterized. Compound crystallizes in the trigonal space group 3. The structure of consists of a discrete mol-ecular complex [Eu(tpa)(HO)] species and the Htpa mol-ecule. In the crystal, the two components are involved in O-H⋯O [ring motif (8)] and C-H⋯π hydrogen-bonding inter-actions. These inter-actions were further investigated by Hirshfeld surface analysis, which showed high contributions of H⋯H, H⋯C/C⋯H and H⋯O/O⋯H contacts to the total Hirshfeld surfaces.
一种基于噻吩丙烯酸（Htpa）的铕（III）配位化合物，三水合三[3 - （噻吩 - 2 - 基）丙烯酸根 - κO1]铕（III） - 3 - （噻吩 - 2 - 基）丙烯酸（1/3），[Eu(CH₂C₄H₂OS)(H₂O)₃]·3CH₂C₄H₂OS 或 [Eu(tpa)(H₂O)₃]·3(Htpa)（其中 tpa 是 Htpa 的共轭碱）已被合成并进行了结构表征。化合物 结晶于三方空间群R3。 的结构由一个离散的分子络合物[Eu(tpa)(H₂O)₃]物种和 Htpa 分子组成。在晶体中，这两个组分参与了 O - H⋯O [环模式 (8)] 和 C - H⋯π 氢键相互作用。通过 Hirshfeld 表面分析对这些相互作用进行了进一步研究，结果表明 H⋯H、H⋯C/C⋯H 和 H⋯O/O⋯H 接触对总 Hirshfeld 表面有很大贡献。
