With the radical 2?,5?-dihydro-4?,5?,5?-trimethyl-spiro-[4,5- diazafluorene-9,2?-imidazol]-1-oxyl L a series of transition metal complexes has been prepared: [ML3](SbF6)2· 4H2O with M2+ = Mn2+ (1), Fe2+ (2), Co2+ (3), Ni2+ (4), Zn2+ (5). Reaction of L with Cu2+ in methanol yielded different products depending on the counterion. In the presence of weakly coordinating anions the Cu(I) complexes [Cu2L3](SbF6)2 · H2O (6), [Cu2L3](OTf)2 · 2MeOH (7) and [Cu2L3](ClO4)2 (8) were formed. Stronger coordinating counter ions gave the complexes CuL2Cl2 · H2O (9), CuL2Br2 · H2O (10) and CuL2(NO3)2 (11). Also the synthesis of [Ag2L3](SbF6)2 · 2H2O (12), Pd(L)Cl2 · H2O (13), Pt(L)Cl2 · H2O (14), Ni(L)Cl2 (15a), Ni(L)Cl2 · 4H2O (15b) and [Ru(bipy)2(L)]Cl2 · 4H2O (16) is reported. The magnetic moments of 1-6 and 10 correspond in the range 200-300 K to those expected for noninteracting spins of the metal ion and the radicals. At low temperatures spin pairing of metal and radical spins is observed for 1-3.
