✦ Synopsis

Abstract

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 C~6~ alkylation and full transition upon lengthening to C~12~. No crossover was observed when the backbone was unfunctionalised, and all three complexes were obtained as unsolvated tetrafluoroborate salts.

In iron(II) spin-crossover compounds, the transition from the 1 A 1 low-spin state at low temperatures to the 5 T 2 high-spin state at elevated temperatures is accompanied by a large increase in metal-ligand bond lengths. The resulting elastic interactions may be pictured as an internal pressure whi
