The central part of the title centrosymmetric dinuclear complex, [Zn(2)(C(7)H(5)O(2))(4)(C(9)H(12)N(2))(2)], has a paddle-wheel conformation with four benzoate ligands bridging two symmetry-related Zn(II) ions. The distorted square-pyramidal coordination environment around the Zn(II) ion is completed by an N atom from a 4-(pyrrolidin-1-yl)pyridine ligand. The Zn⋯Zn separation of 2.9826 (12) Å does not represent a formal direct metal-metal bond. The Zn(II) ion is displaced by 0.381 (1) Å from the mean plane of the four basal O atoms. Two of the C atoms of the pyrrolidine ring are disordered over two sites with refined occupancies of 0.53 (2) and 0.47 (2).
中心对称双核配合物[Zn₂(C₇H₅O₂)₄(C₉H₁₂N₂)₂]的中心部分具有桨轮构象，四个苯甲酸酯配体桥连两个对称相关的Zn(II)离子。Zn(II)离子周围扭曲的四方锥配位环境由来自4-(吡咯烷-1-基)吡啶配体的一个N原子补充完整。2.9826 (12) Å的Zn⋯Zn间距并不代表正式的直接金属-金属键。Zn(II)离子相对于四个基底O原子的平均平面偏移了0.381 (1) Å。吡咯烷环的两个C原子在两个位置上无序，精修占有率分别为0.53 (2)和0.47 (2)。
