摘要

The crystal structures of two amine base salts of dinitramide, the guanidinium 1, and the hydroxyguanidinium 2, have been determined. 1 crystallizes in the triclinic space group P (1) over bar with cell dimensions a = 8.325(2) Angstrom, b = 9.301(2) Angstrom, c = 9.868(2) Angstrom, alpha = 84.73(3)degrees, beta = 69.25(3)degrees, gamma = 67.55(3)degrees, while 2 crystallizes in the noncentric monoclinic space group Pc with cell dimensions a = 7.098(2) Angstrom, b = 3.5160(10) Angstrom, c = 14.358(3) Angstrom, beta = 98.940(10)degrees. The structures of 1 and 2 contain protonated amine cations and dinitramide anions linked by hydrogen bonding. In both structures the conformations adopted by the dinitramine anions can be related to the types of hydrogen bonds it forms with the surrounding amine cations. [References: 22]
