Different cation-protonation patterns in mol-ecular salts of unsymmetrical dimethyhydrazine: C2H9N2·Br and C2H9N2·H2PO3.

ABSTRACT: We describe the syntheses and crystal structures of two mol-ecular salts containing the 1,1-di-methyl-hydrazinium cation, namely 1,1-di-methyl-hydrazin-1-ium bromide, C2H9N2 (+)·Br(-), (I), and 2,2-di-methyl-hydrazin-1-ium di-hydrogen phosphite, C2H9N2 (+)·H2PO3 (-), (II). In (I), the cation is protonated at the methyl-ated N atom and N-H?Br hydrogen bonds generate [010] chains in the crystal. In (II), the cation is protonated at the terminal N atom and cation-to-anion N-H?O and anion-to-anion O-H?O hydrogen bonds generate (001) sheets.
