FIELD: inorganic syntheses. SUBSTANCE: amorphous aluminosilicate derivatives are prepared by reaction of corresponding solid initial material with MOH, wherein M is alkali metal cation or hydroxide. The former can be selected from group including montmorillonite, kaolin, naturally occurring zeolite (e.g. clinoptilonite/heulandite), and also illite, palygorskite, and saponite. MOH can be supplemented by reagent MX, in which X is halogen. Invention also covers aluminosilicate derivatives having general formulas. EFFECT: enabled preparation of derivatives with prevailing tetrahedrally coordinated aluminum increasing number of exchangeable ligands. 13 cl, 16 dwg, 11 tbl
