Abstract

Abstract : 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 charge-transfer complexes at 5 °C or paramagnetic {FeIIILSCoIIHS}2 ones at 35 °C. Abstract : 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.
