| description | A binuclear gadolinium (III) complex was obtained through the interaction of GdCl<sub>3</sub>·6H<sub>2</sub>O, 4,4,4-trifluoro-1-(1-methyl-1<i>H</i>-pyrazol-4-yl)butane-1,3-dione and NaOH in MeOH solution. Molar ration of reagents equal to 1:3:3 was used. Upon recrystallization of wet 1,4-dioxane, an intermediate hydrated complex formed stable crystalline solvate with the composition [(Gd<sub>2</sub>(L)<sub>3</sub>(H<sub>2</sub>O))<sub>2</sub>(C<sub>4</sub>H<sub>8</sub>O<sub>2</sub>)]•2(C<sub>4</sub>H<sub>8</sub>O<sub>2</sub>). The structured of complex was established by single crystal XRD experiment. Furthermore, some photophysical properties of the complex were measured. Thus, the energy of the first exited triplet state for the diketonate ligand was found to be 22400 cm<sup>−1</sup>, which makes 4,4,4-trifluoro-1-(1-methyl-1<i>H</i>-pyrazol-4-yl)butane-1,3-dione a promising ligand for the preparation of highly luminescent Eu<sup>3+</sup> and Sm<sup>3+</sup> complexes. |
