We synthesized a sublimable molecular spin crossover Fe(II) complex based on the Schiff base tridentate ligand qsal-NEt (5-diethylamino-2-((quinolin-8-ylimino)methyl)phenol). The compound undergoes a transition in temperature with thermally induced excited spin state-trapping (TIESST) for high-temperature sweep rates, which can be suppressed by reducing the sweep rate. The X-ray absorption spectroscopy (XAS) studies on the microcrystalline powder confirm the TIESST effect.

Article Synopsis
- Researchers discovered significant quantum tunnelling splitting in the lowest electronic spin levels of mononuclear nickel complexes, indicated by a "clock transition" observed through heat capacity experiments.
- This transition reduces spin-spin interactions between molecules, unlike a cobalt derivative where tunnelling is blocked by symmetry.
- The quantum tunnelling splitting can be chemically adjusted by altering the ligand shell, which influences crystal fields and magnetic properties—key factors for developing stable spin qubits for future quantum computing applications.*
