In the title complex, [Cd(C(2)F(3)O(2))(NO(3))(C(10)H(8)N(2))(2)], the Cd(II) ion is hepta-coordinated by two chelating 2,2'-bipyridyl ligands [Cd⋯N 2.370 (6)-2.416 (6) Å], one carboxyl-ate O atom [Cd⋯O 2.290 (6) Å] from the trifluoro-acetate ligand and two O atoms [Cd⋯O 2.386 (6), 2.633 (6) Å] from a chelating nitrate anion. The trifluoro-methyl fragment is rotationally disordered between two orientations in a 0.640 (7):0.360 (7) ratio. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds contribute to the crystal packing stability.
在标题配合物[Cd(C₂F₃O₂)(NO₃)(C₁₀H₈N₂)₂]中，Cd(II)离子由两个螯合的2,2'-联吡啶配体[Cd⋯N 2.370 (6) - 2.416 (6) Å]、来自三氟乙酸酯配体的一个羧酸根O原子[Cd⋯O 2.290 (6) Å]以及来自一个螯合硝酸根阴离子的两个O原子[Cd⋯O 2.386 (6), 2.633 (6) Å]七配位。三氟甲基片段在两个取向之间以0.640 (7):0.360 (7)的比例发生旋转无序。在晶体中，弱的分子间C-H⋯O氢键有助于晶体堆积的稳定性。
