Abstract

Two new salts of a mononuclear tripodal Fe(ii) complex were prepared, using ClO₄⁻ and Cl⁻. The ClO₄⁻ sample (1) remained HS at low temperatures, similar to the previously reported BF₄⁻ analogue. Crystallising with the Cl⁻ anion (2) led to a markedly different crystal packing arrangement, and engendered SCO activity. This has been correlated to the lower crystal packing density in 2 and the coordination complex conformational differences arising due to the packing motifs of 1 and 2. Further, solvent ordering effects have been proposed to facilitate spin transition behaviour in 2.
