The dinuclear barium-zinc complex, μ-chlorido-1:2κ(2) Cl:Cl-chlorido-2κCl-bis-(2-meth-oxy-ethanol-1κO)bis-(2-meth-oxy-ethanol-1κ(2) O,O')bis-(μ-tri-phenyl-acetato-1:2κ(2) O:O')bariumzinc, [BaZn(C20H15O2)2Cl2(C3H8O2)4], has been synthesized by the reaction of barium tri-phenyl-acetate, anhydrous zinc chloride and 2-meth-oxy-ethanol in the presence of toluene. The barium and zinc metal cations in the dinuclear complex are linked via one chloride anion and carboxyl-ate O atoms of the tri-phenyl-acetate 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-meth-oxy-ethanol ligands (four from two bidentate O,O'-chelate inter-actions and two from monodentate inter-actions), two from bridging tri-phenyl-acetate ligands and one from a bridging Cl donor. The distorted tetra-hedral coordination sphere of zinc comprises two O-atom donors from the tri-phenyl-acetate ligands and two Cl donors (one bridging and one terminal). In the crystal, O-H⋯Cl, O-H⋯O and C-H⋯Cl inter-molecular inter-actions form a layered structure, lying parallel to (001).

Single crystals of the title compound, [Al(iBu)(OCCPh)] or [Al(CH)(CHO)], have been formed in the reaction between tris-(tetra-hydro-furan)-tris-(tri-phenyl-acetato)-neodymium, [Nd(PhCCOO)(THF)], and triiso-butyl-aluminium, Al(iBu), in hexane followed by low-temperature crystallization (243 K) from the reaction mixture. The structure has triclinic ( ) symmetry at 120 K. The dimeric complex [Al(iBu)(OCCPh-μ-κ:κ')] is located about an inversion centre.

The title compound, [AlLa(CHO)(CH)(CHO)]·4CHCH or [{La(PhCCOO)(MeAlOMe)}]·4CHCH, was formed in a reaction between lanthanum tris-(tetra-methyl-aluminate) and tri-phenyl-acetic acid (1:1) with unintended partial oxidation. The tri-phenyl-acetate ligand exhibits μ-κ :κ ' bridging and μ-κ ,':κ semi-bridging coordination modes, forming a dimeric La(μ-OCO) core. The semi-bridging tri-phenyl-acetate group provides additional bonding with an La cation the π-system of one of its phenyl rings.
