English Thermal spin crossover (SCO) was induced in a high-spin Fe^III complex by alkylation of the polyamino ligand backbone. The SCO profile was responsive to chain length with partial crossover observed with C₆ alkylation and full transition upon lengthening to C₁₂. No crossover was observed when the backbone was unfunctionalised, and all three complexes were obtained as unsolvated tetrafluoroborate salts.
