Summary
-
1.
The authors have investigated the reaction between anhydrous Al(ClO4)3 and a number of organic and inorganic solvents. Aluminum perchlorate Al(ClO4)3 dissolves in CH3COOH, (CH3CO)2O, CH3OH, and C2H5OH with complete replacement of the perchlorato groups in the inner coordination sphere of aluminum by molecules of the solvent. In NOCl and N2O4, Al(ClO4)3 undergoes solvolysis to nitrosyl perchlorate and chlorido and nitrato complexes of aluminum. In solvents of medium donor strength — CH3CN, C4H8O, and CH3NO2 — the coordination of the ClO −4 ions to aluminum is retained, but the mode of coordination changes from bidentate to monodentate.

2.
They have developed a method for obtaining Al(ClO4)3·3H2O, and it has been shown that in the latter all three perchlorato groups are monodentate.
-
3.
They have obtained for the first time tetraperchloratoaluminates and pentaperchloratoaluminate of tetrabutylammonium and have shown that they are soluble in CHCl3 and CH2Cl2.
