A bicomponent ion‐pair molecule compound [Co(Brphterpy) 2 ][Co(NCS) 4 ] · 2MeCN was designed and prepared for the construction of multistable functional materials. Due to the different coordination geometries of the cationic and anionic Co II ions, this compound exhibits both thermally induced spin crossover (SCO) and field‐induced single‐ion magnetism (SIM). This represents a rare example of a two‐component system with the coexistence of SIM and SCO behaviors and suggests a simple, yet very efficient strategy for the construction of multistable molecular materials.
