Search of chiral magnetic solitons on the basis of the data on the crystal structure is important from both fundamental and technological points of view. Potential chiral magnetic solitons-hexagonal metal formates [NH4][M(HCOO)(3)] with M2+= Mn, Fe, Co, and Ni and KCo(HCOO)(3) containing dominating left-handed chiral antiferromagnetic helices that compete with interhelix interactions have been identified. The sign and strength of magnetic interactions not only between nearest neighbors but also for longer-range neighbors in the metal formates have been calculated on the basis of structural data. Magnetic structures of these compounds are similar to that of the chiral magnetic soliton Cr1/3NbS2. The interrelation between chiral polarization of crystalline and magnetic structures in the metastable polymorph KCo(HCOO)(3) has been demonstrated.
