文摘

The electronic and geometric structures of a series of iron(II) complexes supported by tetradentate tris(pyrid-2-ylmethyl)amine-type ligands with different numbers of 4-nitropyridine groups, [(PyCH₂)_3鈥?i>n(4-NO₂PyCH₂)_nN] (n = 0鈥?), were examined by X-ray absorption fine-structure and variable-temperature ¹H NMR spectroscopies and theoretical calculations to reveal how the low-spin state is stabilized through 蟺 back-bonding interactions between iron(II) and 4-nitropyridine donor group(s).
