Crystal structure and magnetic properties of (tris-{4-[1-(2-meth-oxy-eth-yl)imidazol-2-yl]-3-aza-but-3-enyl}amine)-iron(II) bis-(hexa-fluorido-phosphate).

ABSTRACT: In the complex cation of the title compound, [Fe(C₂₇H₄₁N₁₀O₃)](PF₆)₂, the tripodal tris-{4-[1-(2-meth-oxy-eth-yl)imidazol-2-yl]-3-aza-but-3-en-yl}amine ligand is coordinated to an Fe^II ion through the nitro-gen atoms of three imidazole and three imino groups. The Fe atom exhibits a distorted octa-hedral geometry. In the crystal, l and d anti-podes are arranged in layers in the bc plane. Weak C?F and C-H?F/O contacts exist between the ligands of the complex cation and the PF₆ ^- anions, generating a three-dimensional network. At 120?K, the Fe^II ion is in a low-spin state, with an average Fe-N bond distance of 1.970?(2)?Å. On heating, the Fe^II ion converts to the high-spin state, as demonstrated by magnetic susceptibility measurements.
