Abstract: The title compound, [Pb₂Zn₂(C₂₂H₁₈N₂O₄)₂Cl₄]·2C₃H₇NO, was synthesized using a step-by-step method and has a slipped sandwich configuration. The coordination environment of the Zn²⁺ ion is distorted square-pyramidal and it is coordinated by N₂O₂ of the Schiff base ligand and chloride; each Pb²⁺ ion is coordinated by the four 6,6'-dimethoxy-2,2'-[o-phenylenebis(nitrilomethylidyne)]diphenolate (L) O atoms and two chloride ions. The Zn^IIPb^II dinuclear unit, through an inversion-symmetry operation, forms a tetrameric complex with double chloride bridges.
