The title compound, [Ni(C14H12BrN2O)2][Ni(C13H12BrN2O)2](ClO4)2 2(MeOH) consists of two mononuclear ([Ni(HL)2]2+ and [NiL 2]) complexes linked by strong hydrogen bonding [O⋯O separations of only 2.430 (5) Å], which is the shortest reported to date for such species.

The structure is reported of a complex containing a trinuclear Zn cation lying on a crystallographic twofold axis. It consists of a tetra­hedral ZnII atom bridging two six-coordinate ZnII atoms in which the two terminal ZnII cations adopt distorted octa­hedral geometries and the central ZnII cation adopts a distorted tetra­hedral geometry.
