Abstract: The title compound, [Ni₂(C₂O₄)(C₄H₁₃N₃)₂(H₂O)₂][B(C₆H₅)₄]₂, contains a centrosymmetric dinuclear oxalato-nickel(II) complex cation in which the oxalate ligand bridges the Ni atoms in a bis-bidentate fashion. The distorted octahedral environment of each Ni atom is completed by the three N atoms of the diethylenetriamine ligand in a fac arrangement, and by one O atom from a water molecule. Tetraphenylborate acts as the counter-anion. The crystal structure shows alternate cationic and anionic layers packed along the [10] direction.
