[CoII2L(NCS)2(SCN)2]: The First Cobalt Complex to Exhibit Both Exchange Coupling and Spin Crossover Effects
摘要:
A spin crossover transition (350 K, μeff =3.15 μB per Co atom; 4.5 K, μeff =0.70 μB per Co atom) and weak antiferromagnetic exchange (2 J=-11.7 cm-1 ) between the octahedral, doubly pyridazine bridged cobalt(II) ions are features of the structurally characterized complex [CoII2 L(NCS)2 (SCN)2 ] (the ligand L is shown).
