Abstract: In the title methanol disolvate complex, [Ni₄(C₁₄H₁₆N₃O₄)₂(ClO₄)₂(C₁₀H₈N₂)₂]·2CH₃OH, the neutral tetranickel(II) system lies on a centre of inversion. The polyhedron around each Ni(II) atom is a square pyramid. The separations of the Ni atoms bridged by the oxamide and carboxyl groups are 5.227 (9) and 5.268 (6) Å, respectively. In the crystal structure, a two-dimensional supramolecular network structure involving O-HO and C-HO hydrogen bonding is observed.
