In the title compound, [Pr(NO(3))(3)(C(10)H(12)N(2)O)(2)], the Pr(III) ion is ten-coordinated by two N and two O atoms from two bidentate 3-(dimethyl-amino)-1-(2-pyrid-yl)prop-2-en-1-one ligands and by six O atoms from three nitrate anions in a distorted bicapped square-anti-prismatic geometry. An extensive three-dimensional network of weak inter-molecular C-H⋯O hydrogen bonds consolidates the crystal packing.
在标题化合物[Pr(NO₃)₃(C₁₀H₁₂N₂O)₂]中，Pr(III)离子由来自两个双齿3-(二甲基氨基)-1-(2-吡啶基)丙-2-烯-1-酮配体的两个N原子和两个O原子以及来自三个硝酸根阴离子的六个O原子以扭曲的双帽四方反棱柱几何构型进行十配位。广泛的三维分子间C—H⋯O弱氢键网络巩固了晶体堆积。
