Spin crossover modulation in a coordination polymer with the redox-active bis-pyridyltetrathiafulvalene (pyTTF) ligand.

A one-dimensional Fe coordination polymer (CP) has been formed which includes the redox-active ligand bis-pyridyltetrathiafulvalene (pyTTF) and a Schiff base-like NO ligand. This CP is both spin crossover (SCO) and redox-active in the solid-state, and chemical oxidation results in SCO modification.
