The title compound, [Fe(2)(C(5)H(5))(2)(C(30)H(22)N(2)O(2))], a 2:1 product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-4-methyl-pyridine, forms a twisted mol-ecular structure in the solid state due to steric effects from the two benzene rings ortho-substituted with ferrocenyl and carbonyl-derived groups. A short intra-molecular C-H⋯π interaction is observed involving a substituted η(5)-C(5)H(4) ring and an ortho H atom of the benzene ring on the opposite side of the mol-ecule. In the crystal structure, there are no classical hydrogen bonds: inter-actions comprise a short C(6)-H⋯π(C(6)) inter-action involving substituted benzene rings and two C-H⋯O=C inter-actions per mol-ecule.
标题化合物[Fe₂(C₅H₅)₂(C₃₀H₂₂N₂O₂)]是2-二茂铁基苯甲酸与2-氨基-4-甲基吡啶反应的2:1产物，由于被二茂铁基和羰基衍生基团邻位取代的两个苯环的空间效应，在固态下形成扭曲的分子结构。观察到一个短的分子内C-H⋯π相互作用，涉及一个取代的η⁵-C₅H₄环和分子另一侧苯环的邻位H原子。在晶体结构中，没有经典的氢键：相互作用包括一个涉及取代苯环的短C(6)-H⋯π(C(6))相互作用和每个分子的两个C-H⋯O=C相互作用。
