a Crystal structure of the pair of Δ-[Co(phendiox)(cth)] (left) and Λ-[Co(phendiox)(cth)] (right) in 1·0.5EtOH at 123 K. Hydrogen atoms, anions, and solvent molecules are omitted for clarity; b calculated direction of the molecular dipole moment; c temperature-dependent bond lengths around Co centers; d temperature-dependent cell parameters normalized with respect to their values at 123 K. Solid lines represent the linear fitting of the thermal expansion parameters; e crystal packing viewed along the a-axis. The b-axis is the polar axis. Cobalt is shown in malachite, oxygen in red, carbon in gray, nitrogen in navy, and chlorine in green. Hydrogen atoms and solvent molecules are omitted for clarity. Hydrogen bonds between perchlorate groups and the Λ-Co motifs are represented by dashed lines.
