In this paper, we investigate the magnetic exchange interaction and magnetization dynamics of two new members [LnRad(NO3)3] family, where Rad is a tripodal nitroxide, Ln Er(III) or Yb(III), having prolate type electron density. Single OK crystal powder X-ray diffraction studies showed that these complexes are isostructural with their previously investigated Y, Gd, Dy, Tm, Tb, Eu, Lu congeners. A magnetometric investigation, supported by ab initio calculations, presence antiferromagnetic coupling between lanthanide ion radical in both compounds estimated J values ≈7 ≈20 cm−1 for Er Yb, respectively (+J Seff∙ S formalism).
