The relationship between chemical structure and spin state in a transition metal complex has an important bearing on mechanistic bioinorganic chemistry, catalysis by base metals, and the design of spin crossover materials. The latter provide an ideal

[FeL2]X2·2H2O (L = 2,6-bis{5-methyl-1H-pyrazol-3-yl}pyridine; X− = BF4− or ClO4−) are readily dehydrated upon mild heating. Anhydrous [FeL2][BF4]2 exhibits an abrupt spin-transition at T1/2 = 205 K, with a 65 K thermal hysteresis loop which na

Iron(II) complex salts of 2,6-di(1,2,3-triazol-1-yl)pyridine (L1) are unexpectedly unstable in undried solvent. This is explained by the isolation of [Fe(L1)4(H2O)2][ClO4]2 and [Fe(NCS)2(L1)2(H2O)2]·L1, containing L1 bound as a monodentate ligand ra

The spin-crossover properties of [Fe(LR)L][ClO4]2 (LR = a chiral PyBox {L1R} or ThioPyBox {L2R} derivative) show subtle differences depending on the tridentate ‘L’ co-ligand.
