在标题分子[Fe（C5 H5）（C7 H6 BrO）]中，取代环的C原子与未取代环相比具有不同的Fe-C键长。在溴乙酰基残基中，Br和O原子是共面的[O-C-C-Br扭转角为5.7（4）°]并且彼此是顺式的。 在C-H O接触的介导下，晶体结构中形成了沿着B轴的螺旋超分子链;羰基-O原子发生分叉。链通过C-H π（未取代的环）相互作用连接成层，所述层沿沿着a轴方向堆叠。
In the title molecule, [Fe(C5H5)(C7H6BrO)], the C atoms of the substituted ring have disparate Fe—C bond lengths compared with the unsubstituted ring. In the bromoacetyl residue, the Br and O atoms are co-planar [the O—C—C—Br torsion angle is 5.7 (4)°] and are syn to each other. Helical supramolecular chains along the b axis are formed in the crystal structure mediated by C—H⋯O contacts; the carbonyl-O atom is bifurcated. The chains are linked into layers by C—H⋯π(unsubstituted ring) interactions that stack along the a-axis direction.
