ABSTRACT

The synthesis and the structure of a new [H3N-(CH2)8-NH3][H2PO4]2 is described. This compound crystallizes in the orthorhombic system, with the centric space group Pbcn and the following unit cell parameters: a = 7.2887 (4), b = 9.1728 (6), c = 23.2169 (19) Å, Z = 4 and V = 1552.23 (18) Å3. The crystal structure has been solved and refined to R = 0.074 and R(w) = 0.173. The [H2PO4]- entities are associated by O---H...O strong hydrogen bonds to form layers. These latters are interconnected with the organic entities via (N)-H...O hydrogen bonds. In this atomic arrangement, H bonds between the different species play an important role in the three-dimensional network. This compound has also been characterized by infrared spectroscopy, solid state MAS-NMR and thermal analysis.
