Abstract

Incorporation of [Co(bpy)3]2+ into the cavities of the three‐dimensional oxalate network structure in [Co(bpy)3][LiCr(ox)3] (see picture) produces chemical pressure that destabilises the normal high‐spin ground state 4T1 to such an extent that the [Co(bpy)3]2+ complex becomes a spin‐crossover complex. It shows a temperature‐dependent equilibrium between the 2E low‐spin and the 4T1 high‐spin states.
