One-dimensional magnetic chain composed of Cu-II and polychlorinated dipyridylphenylmethyl radical: temperature-dependent Jahn-Teller distortion correlated to -conjugation and magnetic properties

摘要

The one-dimensional coordination polymer composed of Cu-II and an organic radical bisPyTM displayed temperature dependent Jahn-Teller distortion, which is correlated to the -conjugation mode at the ligand as well as the magnetic properties. The ferromangetic bisPyTM-Cu-II interaction was enhanced by the reorientation of the Cu-II d(x)(2)-y(2) orbital at low temperature.
