Abstract

Abstract : The cover image compares the molecular spin states of two diastereomers of a spin‐crossover iron(II) complex. Solution‐phase magnetic measurements show the low‐spin state of the heterochiral ( meso ) diastereomer is stabilized relative to its homochiral ( rac ) congener. This reflects a steric clash between phenyl substituents in the rac isomer, which occupies two diagonal quadrants in the molecule. The resultant twisting of the ligand conformation and metal‐coordination sphere explains the observed reduction in the ligand field. More information can be found in the Full Paper by M. A. Halcrow et al. onpage 9067 .
