Measurements of zero‐field NMR of MnSb and related compounds are reported. The spin‐echo signals of Mn 1.00 Sb show quadrupole splittings. Broad unresolved signals have been observed in Mn 2 Sb. Non‐stoichiometric B8‐type compounds Mn 1 + x Sb 1 ‐ y Sn y (Mn, V) 1+x Sb and (Mn, Cr) 1+x Sb show broad unresolved signals or no signals at all. In all compounds the observed frequencies of the Mn 55 and Sb 123 resonances at 4.2 °K arc about 200 and 210 to 220 MHz, respectively. A comparison of the properties of MnSb with the properties of related compounds leads to a metallic band model for MnSb with about six d‐electrons per Mn atom.
