Crystallization Pathways and Hydrogen-Bond Topology Program Spin Crossover in Interconverting Fe(II)-Complex Polymorphs

Puntos clave

• The research aims to explore how crystallization pathways and hydrogen-bond topology influence the spin-transition behavior in Fe(II) complex polymorphs.
• Investigation of a phase-rich Fe(II) spin-crossover system with multiple accessible phases.
• Analysis of crystallization pathways and how they affect hydrogen-bond topology during spin transitions.
• Identified three distinctive phases (4F-1, 4F-2, and others) in the Fe(II) complex system.
• Demonstrated that hydrogen-bond interactions play a critical role in determining the spin-crossover behavior.
