Transition metal silicides crystallizing in the B20 chiral structure with the space group of which $ P2_ {1} 3 $ does not contain an inversion center, have a number of remarkable properties that have been studied for many decades. This article summarizes the results of investigations of the most studied materials of this class MnSi, FeSi and CoSi, which are, in turn, a magnetic metal, a semiconductor and a semimetal. Each of these materials demonstrates the imprint of the influence of spatial symmetry on certain features of the electronic and phonon spectra, some of which have been discovered very recently.
