title: Hysteretic spin crossover in iron(II) complexes of a new pyridine-triazole-pyrazine ligand is tuned by choice of NCE co-ligand.
abstract: A family of three new mononuclear complexes of the general form [Fe(L(pz))2(NCE)2] has been prepared (L(pz) = 4-p-tolyl-3-(2-pyrazinyl)-5-(2-pyridyl)-1,2,4-triazole; E = S, Se, BH3). All three exhibit spin crossover, in two cases with hysteresis, with T1/2 being predictably tuned by varying the coordinated anion.
