In the crystal structure of the title complex, [Ni(2)(C(10)H(20)N(4)O(2))(C(12)H(12)N(2))(2)](ClO(4))(2) or [Ni(dmaeoxd)Ni(dmbp)(2)](ClO(4))(2) {H(2)dmaeoxd 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.
