Cooperative 1D Triazole-Based Spin Crossover FeII Material with Exceptional Mechanical Resilience

A study reported the synthesis, the structural and magnetic characterizations, as well as the first accurate single crystal investigations of both high spin state (HS) and low spin state (LS) states of a new triazolebased spin crossover (SCO) Fe 1-D polymer [Fe(bntrz)3][Pt(CN)4]·H2O. The bntrz ligand was prepared in two steps by reaction of triethyl orthoformate with formylhydrazine and benzylamine under nitrogen atmosphere. Single crystals of [Fe(bntrz)3][Pt(CN)4]·H2O was synthesized via diffusion technique in a fine glass tube by layering an ethanolic solution of the bntrz ligand onto an aqueous solution containing both K2[Pt(CN) 4)]xH2O and Fe(BF4)2·6H2O salts.

Effect of N 4-substituent choice on spin crossover in dinuclear iron(II) complexes of bis-terdentate 1,2,4-triazole-based ligands

Seven new dinuclear iron(II) complexes of the general formula [Fe II2(PMRT)2](BF4)4· solvent, where PMRT is a 4-substituted-3,5-bis{[(2-pyridylmethyl)-amino]methyl}- 4H-1,2,4-triazole, have been prepared in order to investigate the substituent effect on the spin crossover event. Variable temperature magnetic susceptibility and 57Fe Moessbauer spectroscopy studies show that two of the complexes, [FeII2(PMPT)2](BF4) 4·H2O (N4 substituent is pyrrolyl) and [FeII2(PMPhAT)2](BF 4)4 (N4 is N,N-diphenylamine), are stabilized in the [HS-HS] state between 300 and 2 K with weak antiferromagnetic interactions between the iron(II) centers. Five of the complexes showed gradual half spin crossover, from [HS-HS] to [HS-LS], with the following T1/2 (K) values: 234 for [FeII2(PMibT)2](BF 4)4·3H2O (N4 is isobutyl), 147 for [FeII2(PMBzT)2](BF4) 4 (N4 is benzyl), 133 for [FeII 2(PMCF3PhT)2](BF4) 4·DMF·H2O (N4 is 3,5-bis(trifluoromethyl)phenyl), 187 for [FeII2(PMPhT) 2](BF4)4 (N4 is phenyl), and 224 for [FeII2(PMC16T)2](BF 4)4 (N4 is hexadecyl). Structure determinations carried out for three complexes, [FeII2(PMPT) 2](BF4)4·4DMF, [FeII 2(PMBzT)2](BF4)4·CH 3CN, and [FeII2(PMPhAT) 2](BF4)4·solvent, revealed that in all three complexes both iron(II) centers are stabilized in the high spin state at 90 K. A general and reliable 4-step route to PMRT ligands is also detailed.
