The role of crystal chemical factors in the development of conditions for the formation of the magnetic structure of inorganic compounds is shown. A crystal chemical method is proposed to quantitatively estimate the strength of magnetic interactions and to determine magnetic moment orientation based on the structural data. By the example of determining the magnetic structures of two known antiferromagnetics Cs₂CuCl₄ and Sr₂CuO₃ the correspondence between the results obtained by this method and the experiment is shown. It is found that the search for new materials with the sought magnetic structure can be made using the data on the crystal structure of compounds. New Tl₂Cu(CO₃)₂, BaCu₂(AsO₄)₂, BaV₂P₂O₁₀, VOSe₂O₅, KCu(CO₃)F, and A(VO)(XO₄) (A = Li, Na, NH₄, K; X = P and As) magnets containing low-dimensional fragments are found. Magnetic interactions are analyzed; based on the structural data, the sign and strength of magnetic interactions is calculated both inside the low-dimensional fragments and between them; geometrical frustrations are studied in all compounds found.
