Abstract
While magnetic properties of the 1D chain [Fe(hyetrz)3](4-bromophenylsulfonate)2 investigated over the temperature range from 300 K to 2 K show paramagnetic behavior, detailed 57Fe Mössbauer and muon spin relaxation measurements reveal an unexpected spin conversion. Approximately ∼14 % of the high-spin ions are found to convert to the low-spin state with a transition temperature T1/2 ∼ 120 K.
