A pyrazole-based orthogonal ferromagnetically coupled [2 × 2] homoleptic square Cu4 grid: Magnetostructural correlations

Strategic and systematic positioning of polyfunctional groups within the backbone of a pyrazole derived ditopic ligand (PzOAPyz) leads to the formation of an aesthetically looking sophisticated supramolecular self-assembled homoleptic Cu4(μ-O4) square grid which exhibits intramolecular ferromagnetic exchange with an S = 2 magnetic ground state.
