Synthesis and crystal structure of 4-fluorobenzylammonium dihydrogen phosphate, [FC6H4CH2NH3]H2PO4

چکیده
The asymmetric unit of the title salt, [p-FC6H4CH2NH3]+·H2PO4-, contains one 4-fluoro-benzyl-ammonium cation and one di-hydrogen phosphate anion. In the crystal, the H2PO4- anions are linked by O-H⋯O hydrogen bonds to build corrugated layers extending parallel to the ab plane. The FC6H4CH2NH3+ cations lie between these anionic layers to maximize the electrostatic inter-actions and are linked to the H2PO4- anions through N-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network. Two hydrogen atoms belonging to the di-hydrogen phosphate anion are statistically occupied due to disorder along the OH⋯HO direction.

In the crystal structure of the title mol-ecular salt, C6H9N2O2S(+)·H2PO4 (-), the sulfomylalinium cations and the di-hydrogen phosphate anions form independent [100] chains through Ns-H⋯O (s = sulfamo-yl) and O-H⋯O hydrogen bonds, respectively. The chains are cross-linked by Na-H⋯O (a = amine) hydrogen bonds, generating (010) sheets. Two C-H⋯O hydrogen bonds involving diametrically opposite C ...
