Photomagnetic Switching of the Complex [Nd(dmf)₄(H₂O)₃(μ‐CN)Fe(CN)₅]⋅H₂O Analyzed by Single‐Crystal X‐Ray Diffraction

Abstract

X-ray vision: Single-crystal XRD experiments (see picture) reveal the excited-state structure of the photomagnetic heterobimetallic title complex. The system shows a decrease in all the iron-ligand bond lengths, suggesting that photoexcitation involves a ligand-to-metal charge transfer or a change in the superexchange coupling between the metal centers.
