One synthesis: two redox states. Temperature-oriented crystallization of a charge transfer {Fe 2 Co 2 } square complex in a {FeIILSCoIIILS} 2 diamagnetic or {FeIIILSCoIIHS} 2 paramagnetic state

The reaction of [Fe III (Tp)(CN) 3 ] − with [Co II (vbik) 2 (S) 2 ] 2+ leads selectively to the crystallization of cyanide-bridged diamagnetic {FeIILSCoIIILS} 2 squares at 5 °C or paramagnetic {FeIIILSCoIIHS} 2 ones at 35 °C. The diamagnetic crystal phase can be converted to a paramagnetic one upon...

Summary:The reaction of [Fe III (Tp)(CN) 3 ] − with [Co II (vbik) 2 (S) 2 ] 2+ leads selectively to the crystallization of cyanide-bridged diamagnetic {FeIILSCoIIILS} 2 squares at 5 °C or paramagnetic {FeIIILSCoIIHS} 2 ones at 35 °C. The diamagnetic crystal phase can be converted to a paramagnetic one upon heating and it shows photomagnetic effects at low temperature.
