. Solid (R)-3·MeNO 2 exhibits an unusualv ery gradual, but discontinuoust hermals pin-crossover with an approximate T1 = 2 of 350 K. The discontinuity around 240 Kl ies well below T1 = 2 , and is unconnected to ac rystallographic phase change occurring at 170 K. Rather,i tc an be correlated with ag radual ordering of the ligand conformation as the temperature is raised. The other solid compounds either exhibit spin-cross-

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.
