Iron in square planar coordination has exceptional electronic and magnetic properties and reactivity. In this project, we synthesize soluble, well-defined molecular complexes with square planar N4-Fe units and determine their magneto-electronic signatures by combining pNMR, EPR, quantum chemistry, and Mössbauer measurements. This enables the disentanglement of intra- and intermolecular effects and allows for the systematic optimization of molecular and related solid-state systems with iron as the central element.
