Unusual isomorphism in crystals of organic solvates with hydrazine and water

Author affiliations

Abstract

An unusual isomorphism of 18-crown-6 hydrazine disolvate C12H24O6·2N2H4 (1) and 18-crown-6 tetrahydrate (2) is observed. The isomorphous substitution of hydrazine by water molecules is found for the first time in the structures of tetrabutylammonium acetate hydrazine solvates hydrous Bu4N+AcO·0.9(N2H4)·0.1(H2O) (3) and anhydrous Bu4N+AcO·N2H4 (4). Surprisingly, the nature of these isomorphous relationships is completely different from the well-known isostructurality of organic hydrogen peroxide/water solvates.
