在一个新的Cu(II)分子链中观察到了一个原始的磁双稳态和一个热致变色转变。热结构的研究揭示了在Cu(II)的配位球的变化,在低温下由更明显的Jahn-Teller效应驱动。这些扭曲引起逐渐的颜色变化。在10 K下的结构研究表明分子链的二聚化,与在30 K下观察到的突然的磁性转变一致。
An original magnetic bistability and a thermochromic transition are observed in a new Cu(II) molecular chain. Thermal structural studies reveal changes in the Cu(II) coordination sphere, driven by a more pronounced Jahn-Teller effect at low temperature. These distortions provoke a gradual color change. The structural study at 10 K shows a dimerization of the molecular chain, in agreement with the abrupt magnetic transition observed at 30 K.
