EPR spectra of Mn 2+ in northupite single crystals were measured at X‐band and room temperature. Only one isotropic sextet is recorded for all orientations. The hyperfine splitting constant of 81 · 10 −4 cm −1 is in the expected range for Mn 2+ in six‐fold coordination. The very small zero field splitting gives a strong evidence that the occupied site by Mn‐ion is the Mg‐site in consistence with the preference of Mn 2+ for such a substitution.
