Novel co-operative magnetic properties of decamethylmanganocenium 2,3-dichloro-5,6-dicyanobenzoquinoneide, 3[Mn(C5Me5)2]:+[DDQ]˙–
Abstract
The electron-transfer salt 3[Mn(C5Me5)2]:+[DDQ]˙–, isomorphous to orthorhombic [Fe(C5Me5)2]˙+[DDQ]˙–, has been prepared. It exhibits a complex field-dependent magnetic pahse diagram at low temperatures with evidence for ferromagnetic coupling as well as a low moment state below 4 K for zero-field cooled samples.
