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 dmaeoxd2- ligand is in a cis conformation and bridges two NiII 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 dmaeoxd2- 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.

The title compound, [Co(C4H4O5)(C6H6N4S2)(H2O)]·3H2O, displays a distorted octa­hedral coordination geometry. The tridentate oxydiacetate dianion chelates the CuII atom in the meridional mode. In the crystal packing, hydro­philic and hydro­phobic layers are arranged in an alternating manner. In addition, a three-dimensional hydrogen-bonding framework and π–π stacking are present.

In the crystal structure of the title complex, [CuNi(C10H20N4O2)(C12H8N2)2(H2O)](ClO4)2·0.5CH4O or [CuNi(dmae­oxd)(phen)2(H2O)](ClO4)2·0.5CH3OH {H2dmaeoxd is N,N'-bis­[2-(dimethyl­amino)ethyl]oxamide and phen is 1,10-phen­anthroline}, the deprotonated dmaeoxd2- ligand is in a cis conformation and bridges the CuII and NiII atoms. The CuII atom is located in a slightly distorted square-based pyramidal environment, while the NiII atom is in an irregular octa­hedral environment. The binuclear Cu-Ni units inter­act with each other via [pi]-[pi] inter­actions, which results in an extended chain along the b axis.
