Environmental Control of Spin State Through Solution Aggregation

21 January 2025, Version 1
Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

Direct environmental control of the spin state is observed in alkyl sulfate Fe(III) complexes of 5-OMeSal2trien. High spin, low spin and mixed spin state responses are controlled by the aggregation properties of the dodecyl and octadecyl sulfate anions. Smaller particles favour the LS state due to size constraints, while larger aggregate formation favours the HS state allowing it to take up more space in a larger, relaxed particle.
