[mu]-{N,N'-Bis[2-(dimethyl­amino)ethyl]oxamidato(2-)}-1[kappa]²O,O':2[kappa]⁴N,N',N'',N'''-bis­(4,4'-dimethyl-2,2'-bipyridine-1[kappa]²N,N')dinickel(II) bis­(perchlorate)

In the crystal structure of the title complex, [Ni₂(C₁₀H₂₀N₄O₂)(C₁₂H₁₂N₂)₂](ClO₄)₂ or [Ni(dmaeoxd)Ni(dmbp)₂](ClO₄)₂ {H₂dmaeoxd is N,N'-bis­[2-(dimethyl­amino)ethyl]oxamide and dmbp is 4,4'-dimethyl-2,2'-bipyridine}, the deprotonated dmaeoxd^2- ligand is in a cis conformation and bridges two Ni^II atoms, one of which is located in a slightly distorted square-planar environment, while the other is in an irregular octa­hedral environment. The cation is located on a twofold symmetry axis running through both Ni atoms. The dmaeoxd^2- ligands inter­act with each other via C-H...O hydrogen bonds and [pi]-[pi] inter­actions, which results in an extended chain along the c axis.
