摘要：

The structure of intercalation complexes of aluminum hydroxide with lithium salts is investigated by X-ray diffractometry and by Al-21,Li- 7, and H-1 NMR. The lithium ions occupy vacant positions in the octahedral voids of aluminum hydroxide, and all atoms of gibbsite change localization. Parameters of rite Al-27 and Li-7 quadrupole and H-1 dipole-dipole interaction tensors in anhydrous and aqueous intercalates of gibbsite with lithium salts are determined. A mechanism is suggested for the interaction of gibbsite with aqueous solutions of lithium salts.
