Aliphatic Chains and External Pressure as Tools for Fine-Tuning Spin Transition Temperature and Cooperativity.

ABSTRACT: In switchable spin crossover (SCO) molecular materials, control of their critical temperature and cooperativeness is essential for practical applications. This requires systematic fine-tuning of the molecular packing in the crystal. Therefore, here we report on the synthesis and characterization of a series of Fe^II SCO complexes, {Fe^IIL}(ClO₄)₂, derived from a tripodal tren-based imino-methyl-pyridine hexadentate-type ligand L with alkoxy chains of varying lengths (C3 to C22). The complexes crystallize in the monoclinic P2₁/c space group, displaying an identical coordination core. The crystal packing, modulated by the length of the alkoxy chains, is governed by the amphiphilic nature of the complexes, where the hyd
