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 4 T 1 to such an extent that the [Co(bpy) 3 ] 2+ complex becomes a spin‐crossover complex. It shows a temperature‐dependent equilibrium between the 2 E low‐spin and the 4 T 1 high‐spin states.
