Ligand field design enables quantum manipulation of spins in Ni²⁺ complexes.

ABSTRACT: Creating the next generation of quantum systems requires control and tunability, which are key features of molecules. To design these systems, one must consider the ground-state and excited-state manifolds. One class of systems with promise for quantum sensing applications, which require water solubility, are d⁸ Ni²⁺ ions in octahedral symmetry. Yet, most Ni²⁺ complexes feature large zero-field splitting, precluding manipulation by commercial microwave sources due to the relatively large spin-orbit coupling constant of Ni²⁺ (630 cm^-1). Since low lying excited states also influence axial zero-field splitting, D, a combination of strong field ligands and rigidly held octahedral symmetry can ameliorate these challenges. Towards the
