【 摘 要 】

The dinuclear barium–zinc complex, μ-chlorido-1:2κ2Cl:Cl-chlorido-2κCl-bis­(2-meth­oxy­ethanol-1κO)bis­(2-meth­oxy­ethanol-1κ2O,O′)bis­(μ-tri­phenyl­acetato-1:2κ2O: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 Ba⋯Zn 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—H⋯Cl, O—H⋯O and C—H⋯Cl inter­molecular inter­actions form a layered structure, lying parallel to (001).
