[Eu(PMTFP)_3·(H_2O))2)·H_2O的单晶用ENRAF-NONIUS CAD4型四圆衍射仪收集衍射数据进行结构分析。最终偏离因子R=0.046。晶体属空间群P2_1/a。晶胞参数a=16.055(2),b=16.016(3),c=17.752(5),β=106.41(2)°,Z=4。结构分析证实,Eu与配体的六个氧以及二个水分子中的氧形成八配位的稍畸变三角十二面体结构。氢键是连按配位分子形成晶体的主要键力,[Nd(PMTFP)_3·(H_2O)_2]·H_2O单晶的晶胞参数与之相近,有类似的分子与晶体结构。 [Eu (PMTFP) _3 · (H_2O)) 2) · H_2O single crystals were analyzed by diffraction data collected using the ENRAF-NONIUS CAD4 four-circular diffractometer. The final deviation factor R = 0.046. The crystal belongs to space group P2_1 / a. Cell parameters a = 16.055 (2), b = 16.016 (3), c = 17.752 (5), β = 106.41 (2) °, Z = 4. Structural analysis confirmed that Eu forms a slightly distorted triangular dodecahedron structure with octacoordination of the six oxygen atoms of the ligand and oxygen in the two water molecules. Hydrogen bonding is the main bond force of the coordination crystal to form the crystal. The lattice parameters of the [Nd (PMTFP) _3 · (H_2O) _2] · H_2O single crystal are similar to each other, and have similar molecular and crystal structures.
