The dinuclear barium-zinc complex, -chlorido-1:2²Cl:Cl-chlorido-2Cl-bis­(2-meth­oxy­ethanol-1O)bis­(2-meth­oxy­ethanol-1²O,O')bis­(-tri­phenyl­acetato-1:2²O:O')bariumzinc, [BaZn(C₂₀H₁₅O₂)₂Cl₂(C₃H₈O₂)₄], has been synthesized by the reaction of barium tri­phenyl­acetate, anhydrous zinc chloride and 2-meth­oxy­ethanol in the presence of toluene. The barium and zinc metal cations in the dinuclear complex are linked via one chloride anion and carboxyl­ate O atoms of the tri­phenyl­acetate ligands, giving a BaZn separation of 3.9335 (11) Å. The irregular nine-coordinate BaO₈Cl coordination centres comprise eight O-atom donors, six of them from 2-meth­oxy­ethanol ligands (four from two bidentate O,O'-chelate inter­actions and two from monodentate inter­actions), two from bridging tri­phenyl­acetate ligands and one from a bridging Cl donor. The distorted tetra­hedral coordination sphere of zinc comprises two O-atom donors from the tri­phenyl­acetate ligands and two Cl donors (one bridging and one terminal). In the crystal, O-HCl, O-HO and C-HCl inter­molecular inter­actions form a layered structure, lying parallel to (001).
