文摘

The "templating" K crown ether cation allows for the preparationof soluble layered oxalate-based bimetallic magnets, as in [K(18-crown-6]₃{Mn₃(H₂O)₄[Cr(ox)₃]₃}, with an unprecedented bidimensional polymeric anionic network that involves both oxalato bridgesand H bonds. As in other 2D oxalate-bridged compounds, thecompound behaves as a soft ferromagnet, with the onset ofmagnetic ordering occurring at 3.3 K.
