Abstract: Aqueous reaction of Zn(II) and Mn(II) salts with ammonium tetrasulfidometalate (NH4)2[MS4] (M = Mo, W) in the presence of ammonia or ethane 1,2-diamine (en) or propane 1,2-diamine (1,2-pn) results in the formation of [M'(L)n][MS4] (M’ = Zn or Mn; L = NH3 or en or 1,2-pn). Using this strategy, Mn doped Zn complex of formula [Zn0.99Mn0.01(en)3][MS4], which exhibits characteristic hyperfine ESR spectra have been synthesized. The synthetic aspects, spectral and thermal characterization are described.
