The title complex, [Ni(2)(C(6)H(2)N(3)O(7))(2)(C(10)H(20)N(4)O(4))], contains a centrosymmetric binuclear unit in which the oxamide ligand (located on a centre of symmetry) acts in a bis--tetra-dentate fashion and the picrate anion binds to nickel(II) in a bidentate mode. The Ni(II) atom displays a distorted octa-hedral coordination with axial elongation. The binuclear mol-ecules are linked by inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a two-dimensonal supra-molecular network extending parallel to (100).

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.
