A behavioural difference between an iron(II) grafted polyphosphazene and its small molecule cyclophosphazene analogue

摘要

Mdssbauer and electronic absorbance spectroscopy along with variable temperature magnetic moment measurements demonstrate that a cyclotriphosphazene substituted with an iron(II)-bis-2,6-di(lH-pyrazoly-yl)pyridine moiety (1) and its polyphosphazene analogue (2) differ significantly in magnetic behaviour.
