Enhancement of the magnetic susceptibility of an organic complex
Abstract
The magnetic properties of [1,2-di(4-pyridinio)ethylene]x2x+[1,2-di(4-pyridyl)ethylene]1-x(7,7,8,8-tetracyano-p-quinodimethane)32x–,(H2DPE)x2x–(DPE)1–x(TCNQ)32x–, are dependent upon the stoicheiometry: for x > ½ the susceptibility decreases with increasing values of x whereas for x≈½ it is enhanced above the Curie law value.
