It is a challenge to reversibly switch both magnetism and polarity using light irradiation. Herein we report a linear Fe 2 Co complex, whereby interconversion between Fe III LS (μ‐CN)Co II HS (μ‐NC)Fe III LS (LS=low‐spin, HS=high‐spin) and Fe III LS (μ‐CN)Co III LS (μ‐NC)Fe II LS linkages could be achieved upon heating and cooling, or alternating laser irradiation at 808 and 532 nm. The electron spin arrangement and charge distribution were simultaneously tuned accompanying bidirectional metal‐to‐metal charge transfer, providing switchable polarity and magnetism in the complex.
