Crystal structure of a mixed-ligand dinuclear Ba—Zn complex with 2-meth­oxy­ethanol having tri­phenyl­acetate and chloride bridges

The dinuclear barium–zinc complex, μ-chlorido-1:2κ(2) Cl:Cl-chlorido-2κCl-bis­(2-meth­oxy­ethanol-1κO)bis­(2-meth­oxy­ethanol-1κ(2) O,O′)bis­(μ-tri­phenyl­acetato-1:2κ(2) O:O′)bariumzinc, [BaZn(C(20)H(15)O(2))(2)Cl(2)(C(3)H(8)O(2))(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 BaO(8)Cl 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).
