We determine the valence electron density and the electron band structure of stibnite, bismutinite, guanajuatite and antimonelite using the density functional theory. All the compounds present similar electronic properties and exhibit a quasi-1D character. We perform a detailed analysis of the charge topology, the atomic static charges and volumes.
