“…Transition metal complexes of 1,2,4-triazoles have attracted significant attention over the last two decades (Kunkeler et al, 1996 ; Haasnoot, 2000 ; Klingele and Brooker, 2003 ; Klingele et al, 2005 ; Kitchen and Brooker, 2008 ; Aromí et al, 2011 ; Miller and Brooker, 2016 ; Bushuev et al, 2017 ; Chen et al, 2017 , 2018 ; Feltham et al, 2017 ; Murphy et al, 2017 ; Rodríguez-Jiménez et al, 2017 ; Clements et al, 2018 ; Hogue et al, 2018 ; Li et al, 2018 ; Liu et al, 2018 ; Zenere et al, 2018 ). Much of this interest has stemmed from the spin crossover (SCO) phenomenon that is frequently observed in octahedral iron(II) complexes of 1,2,4-triazoles (Kunkeler et al, 1996 ; Haasnoot, 2000 ; Klingele and Brooker, 2003 ; Klingele et al, 2005 ; Kitchen and Brooker, 2008 ; Miller and Brooker, 2016 ; Bushuev et al, 2017 ; Chen et al, 2017 , 2018 ; Feltham et al, 2017 ; Murphy et al, 2017 ; Rodríguez-Jiménez et al, 2017 ; Clements et al, 2018 ; Hogue et al, 2018 ; Li et al, 2018 ; Liu et al, 2018 ; Zenere et al, 2018 ). Additionally, exchange coupling between triazole bridged metal centers has resulted in families of dinuclear, trinuclear and even polymeric complexes being targeted for the development of magnetically interesting complexes (Hogue et al, 2018 ).…”
