Tetradentate Janus heads L − : Staples for the construction of square tetranuclear clusters of the type [M 4 L 8 ] 1 (M=Ni, Zn; see picture). The [2×2] grids 1 are generated in a one‐pot reaction by self‐assembly. The magnetic susceptibility of the nickel complex [Ni 4 L 8 ] Ni‐1 exhibits an increase of χ T at low temperature due to intramolecular ferromagnetic coupling of the Ni ions.
