The title compound, Ni(2)(C(2)O(4))(C(4)H(13)N(3))(2)(H(2)O)(2)(2).2H(2)O, contains a dinuclear oxalato-bridged nickel(II) complex cation. The structure determination reveals the presence of a centrosymmetric binuclear complex where the oxalate ligand is coordinated in a bis-bidentate mode to the Ni atoms. 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. PF(6)(-) acts as counter-anion. A two-dimensional network of hydrogen bonds links the cations and anions and stabilizes the structure.
标题化合物Ni₂(C₂O₄)(C₄H₁₃N₃)₂(H₂O)₂₂·2H₂O包含一个双核草酸根桥联的镍(II)配合物阳离子。结构测定表明存在一个中心对称的双核配合物，其中草酸根配体以双齿双配位模式与镍原子配位。每个镍原子的扭曲八面体环境由二乙烯三胺配体的三个氮原子以面式排列以及一个水分子中的一个氧原子完成。PF₆⁻作为抗衡阴离子。二维氢键网络连接阳离子和阴离子并稳定结构。
