Abstract

Mössbauer measurements on ¹²⁹I in iodo (bispyrrolidinedithiocarbamato) Fe^III show the occurence of magnetic ordering at 2.18°K and relaxation effects in the paramagnetic region. The transition is confirmed by measurements on ⁵⁷Fe. The effective magnetic field at the ¹²⁹I nucleus at 1.4°K is 66^± 2kG and is perpendicular to the direction of the iron-iodine bond. The number of p and s holes in the (5s)² (5p)⁶ valence shell of iodine is determined from the values of the quadrupole coupling constant and the isomer shift.
