Summary:A novel nitronyl nitroxide biradical-based MnII2DyIII2 compound [Dy2Mn2(hfac)10(NITPhPybis)2] has been designed and assembled successfully, representing the first example of nitronyl nitroxide-MnII-LnIII compounds and expanding the realm of radical-metal based magnetic materials. DC magnetic susceptibility studies reveal the existence of ferromagnetic Dy-nitronyl nitroxide interaction and strong antiferromagnetic interaction between direct coordinated NO group and Mn(II) ion. The rational design of a polynuclear 2p-3d-4f cluster made of MnII ions, DyIII ions and functionalized nitronyl nitroxide biradicals is presented. The cluster represents the first the nitronyl nitroxide-MnII-LnIII complex. [Display omitted] •The first nitronyl nitroxide biradical-based MnII-DyIII heterometallic cluster has been successfully obtained.•Compound possesses a centrosymmetric annular heterometallic tetranuclear structure.•DC magnetic susceptibility studies reveal the ferromagnetic interaction between the Dy(III) ion and mono-radical.
