Synthesis, structure and magnetic properties of a novel lead(II) complex containing nitronyl nitroxide radicals

A novel lead(II) complex [Pb(NIT2Py)2(NO3)2] has been prepared and characterized. The lead(II) ion is coordinated with two bidentate nitronyl nitroxide and two nitrate anions. There is antiferromagnetic interaction between the coordinated nitronyl nitroxides (J = −19.35 cm−1). We observe the sixth periodic IVA group metal element Pb(II) ion providing an effective pathway for the magnetic exchange interaction between nitronyl nitroxide radicals.
