Abstract

Three iron(II) complexes with 3-(p-bromophenyl)-4-phenyl-5-(2-pyridyl)-1,2, 4-triazole (L), trans-[FeL₂(NCS)₂] (1), trans-[FeL ₂(NCS)₂]·2MeOH (1·2MeOH), and trans-[FeL₂(NCSe)₂] (2), have been synthesized and characterized by elemental analysis, FT-IR, ESI-MS, and single crystal X-ray crystallography. Crystallographic studies reveal that all the complexes contain a distorted octahedral [FeN₆] core with two trans NCS(Se)^- ions. Each L adopts a chelating bidentate coordination via one N of pyridyl and one N of triazole. Magnetic susceptibility measurement indicated that both 1 and 1·2MeOH are in a high-spin state from 2 to 300 K.
