C 10 H 18 NO 4 P, orthorhombic, Aba2(no. 41), a =7.218(1) Å, b =36.600(7) Å, c =9.188(2) Å, V =2427.2 Å 3 , Z =8, R gt (F) =0.043, wR ref (F 2 ) =0.105, T =296 K. Source of materialAhydrothermalreaction was carried out in a23mlTeflon-lined stainless steel Parr hydrothermalreaction vessel at 150°C for 2d. Phosphoric acid (0.03 ml, 0.5 mmol), 4-phenyl-butylamine (0.24 ml, 1.5 mmol), and water (3.0 ml) were allowed to react. The pH value of the solution before and after the reaction was 11.3 and 7.5, respectively. Thesolid products were recovered by vacuum filtration and washedwith water. Colorless platy crystals suitable for analysis were obtained. The yield of the crystalline product was~40 %based on phosphorous. Experimental detailsHydrogen atomswere placed in calculated positions and refined as riding except those of the hydroxylg roup in H 2 PO 4 -which werelocated in differenceFouriermaps, and their positions and isotropic displacement parameters were refined. The Flack parameter was -0.03(15). DiscussionThe KH 2 PO 4 (KDP) family is one of the most important classes in non-linear optics and ferroelectrics due to its non-centrosymmetric structure [1,2]. Many KDP analogues have been reported, and the arrangement of H 2 PO 4 -can be controlled by the species of counter cations incorporated in the structure [3][4][5][6][7]. A hydrogen bond between the counter cations and dihydrogenphosphate anions is ak ey variable to construct an oncentrosymmetric array of H 2 PO 4 -with very shortO×××Odistances.The title crystal structure is built up from a4-phenylbutylammonium cation and ad ihydrogenphosphate anion. The detailed analysis of H 2 PO 4 -confirms thepositions of oxo-andhydroxyl groups by comparing the bond distances and angles, i.e., d(P-O) of 1.4942(2) Åa nd 1.5369(3) Åa re shorter than d(P-OH) of 1.5396(2) Åand 1.5647(2) Å, and ÐO-P-O =114.2(2)°is wider than ÐHO-P-OH =109.0(1)°. Each anion H 2 PO 4 -is strongly hydrogen bonded to one another forming "macroanionic" layers perpendicular to [010]

In the title compound, 4C7H10N+·2H3O+·P6O18 6−, the complete cyclohexaphosphate anion is generated by crystallographic inversion symmetry. In the crystal, the H3O+ ions and the [P6O18]6− anions are linked by O—H⋯O hydrogen bonds, generating infinite layers lying parallel to the ab plane at z = 1/2. These layers are interconnected by the organic cations, which establish N—H⋯O hydrogen bonds with the [P6O18]6− anions.
