Abstract: The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn₂(C₇H₅O₂)₄(C₁₂H₁₀N₂)₂], contains four bridging benzoate groups and two terminal trans-1-(2-pyridyl)-2-(4-pyridyl)ethylene (L) ligands. The inversion center is located between the two Zn^II atoms. The octahedral coordination around the Zn^II atom, with four O atoms in the equatorial plane, is completed by an N atom of the L molecule [Zn-N = 2.0198 (15) Å] and by the second Zn^II atom [ZnZn = 2.971 (8) Å]. The Zn^II atom is 0.372 Å out of the plane of the four coordinating O atoms.
