The stepwise synthesis of the new ligand 4,5-diphenyl-3-pyridyl-1,2,4-triazole (phppt) from N-phenyl-pyridine-2-thiocarboxamide and benzohydrazide is reported. Two iron(II) complexes, [Fe(phppt)(2)(SCN)2]center dot 2MeOH and [Fe(phppt)(2) (SeCN)(2)]center dot Et2O, have been prepared and structurally characterised at 90 K, showing that both complexes are high spin (HS). The Mossbauer spectrum of [Fe(phppt) 2(SeCN) 2]center dot 1.5MeOH is consistent with the iron(II) ion being HS at 5.2 K.
