ResumoEPR studies have been carried out in Mn2+-doped single crystals of [M(H2O)6]SnF6 (M Zn, Co) at different temperatures using X-band microwave frequency. Mn2+ has been found to substitute for Zn2+ or Co2+ exhibiting a unique magnetic complex with z-axis directed long the c-axis of the crystals. Observation of resolved Mn2+ spectrum in [Co(H2O)6]SnF6 and broadening of the resonance lines on cooling the crystals have been explained on the basis of host spin-lattice relaxation narrowing. The T1 of Co2+ has been estimated to be ≈ 1.8 × 10−12 s at 293 K.
