Ferromagnetic interactions of μ-NO3− bridged 2-D silver (I) complex with imino nitroxide radical

A first μ-NO3− bridged and self-assembled 2-D silver (I) complex [Ag(I)(im-mPy)NO3)] (1) (im-mPy=(2-(3-pyridyl)-4,4,5,5-tetramethyl-2-imidazolin-1-ol), has been prepared and structurally characterized. Temperature dependence of susceptibility measurements shows a weak ferromagnetic coupling between im-mPy radicals with J=3.3 cm−1.
