The title dinuclear complex, [Fe2Br4(C13H9N4)2], which lies on an inversion center, features two approximately planar bis-(pyridin-2-yl)pyrazole (bpypz(-)) ligands [maximum deviation = 0.082 (3) Å] and four bromide ions. Each Fe(III) ion is octa-hedrally coordinated by four N atoms of two bpypz(-) ligands and two Br ions. π-π stacking inter-actions [centroid-centroid distances = 3.7004 (17)-4.0123 (18) Å] are observed between pyridyl and pyrazole rings, and between pyridyl and pyridyl rings of adjacent complex mol-ecules.
标题为双核配合物[Fe₂Br₄(C₁₃H₉N₄)₂]，它位于一个倒转中心上，其特征是有两个近似平面的双-(吡啶-2-基)吡唑(bpypz⁻)配体[最大偏差 = 0.082 (3) Å]和四个溴离子。每个Fe(III)离子由两个bpypz⁻配体的四个N原子和两个Br离子八面体配位。在吡啶基和吡唑环之间以及相邻配合物分子的吡啶基和吡啶基环之间观察到π-π堆积相互作用[质心-质心距离 = 3.7004 (17)-4.0123 (18) Å]。
