Orthogonal arrangement of iminonitroxides in [Cu-I(immepy)(2)](PF6) (1) and [Ag-I(impy)(2)](PF6) (2) results in propagation on intramolecular ferromagnetic interaction between coordinating iminonitroxides through these diamagnetic ion. In 1, iminonitroxides coordinate to the Cu-I ion in a tetrahedral fashion, the dihedral angle between coordinating iminonitroxides being 88.7 degrees. Magnetic susceptibility and epr measurements for 1 show the typical ferromagneic behavior with large zero field splitting (2J = 91(1) cm(-1) (H = -2JS(1) . S-2); D = 3.62 cm(-1)). In 2, the four coordination sites of Ag-I ion were completed with two iminonitroxides and the dihedral angle between the iminonitroxides is 79.2 degrees. Temperature dependence of teh epr spectra for frozen ethanol solution of 2 shows that the intramolecular mangetic interaction between radicals is ferromagnetic (theta = 4 K).
