In the colourless title compound, [Pr(CF3O3S)3(CH3CN)3] n , the three trifluoro-methane-sulfonate anions form three bridges via O:O'-coordination between two Pr(III) atoms. The structure contains [Pr(NCMe)3-μ2(OTf)3-Pr(NCMe)3-μ2(OTf)3] n (NCMe is acetonitrile; OTf is trifluoromethanesulfonate) chains parallel to the a axis. The Pr(III) atom is nine-coordinate in a distorted tricapped trigonal-prismatic environment.
在无色标题化合物[Pr(CF₃O₃S)₃(CH₃CN)₃]ₙ中,三个三氟甲磺酸根阴离子通过两个Pr(III)原子之间的O:O'配位形成三个桥。该结构包含平行于a轴的[Pr(NCMe)₃-μ₂(OTf)₃-Pr(NCMe)₃-μ₂(OTf)₃]ₙ链(NCMe为乙腈;OTf为三氟甲磺酸根)。Pr(III)原子在扭曲的三帽三角棱柱环境中为九配位。
