Anomalously high coercive field magnets with large remanence magnetizations have been prepared from electron‐transfer salts of tetracyanoethylene and Mn II (porphyrin). These magnets exhibit metamagnetic‐like behavior at low temperature but, anomalously, show hysteresis with a large remanent magnetization. Metamagnets that display large coercivity and remanence magnetizations, especially when these values are large, may lead to new technologically important materials.
