A spin crossover transition (350 K, μ eff =3.15 μ B per Co atom; 4.5 K, μ eff =0.70 μ B 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 [Co II 2 L(NCS) 2 (SCN) 2 ] (the ligand L is shown).
