Crystal structure and thermal behavior of two new organic monosulfates NH3(CH2)5NH3SO4 1.5H2O and NH3(CH2)9NH3SO4 H2O

Synthesis, characterisation, phase transitions and electrical properties of 4-benzylpyridinium dihydrogenmonophosphate and monohydrogensulfate

“…Colourless crystals of 4-BP and 4-BPS were grown in two stages: first, a batch of seed material was prepared from an aqueous solution containing a stoichiometric mixture of 4-benzylpyridine C 6 . A small specimen was selected and with an Enraf-Nonius CAD-4 diffractometer using ω-2θ scan mode 2372 reflections with Miller indices −2 ≤ h ≤ 10, 0 ≤ k ≤ 11, −16 ≤ l ≤ 16 were collected.…”

“…These compounds appeared later to be interesting starting materials for further syntheses. Numerous structures of monophosphate and monosulfate salts have been described; NH 3 (CH 2 ) 2 NH 3 (H 2 PO 4 ) 2 [1], NH 3 (CH 2 ) 2 NH 3 (H 2 PO 4 ) 2 H 3 PO 4 [2], NH 3 (CH 2 ) 2 NH 3 HPO 4 [3], NH 3 (CH 2 ) 3 [6]. In the present work we describe the two crystal structures of the 4-benzylpyridinium dihydrogenmonophosphate/monohydrogensulfate and report some results of impedance spectroscopy and calorimetric measurements (hereafter abbreviated to 4-BP and 4-BPS).…”

1,5-Diaminopentane As A Structure-Directing Agent for Zincophosphate Networks: Zn3(PO4)2(C5H14N2)2·3H2O and C5H16N2·Zn3(PO4)2(HPO4)·H2O

“…Both PO 4 groups in 1 are close to regular tetrahedra (mean P1-O = 1.538 Å, angular variance = 2.7°2; mean P2-O = 1.541 Å, angular variance = 1.4°2) and all the O atoms link to an adjacent Zn atom, thus there are no terminal or "dangling" P=O or P-OH bonds [13] in 1. The geometrical parameters for the two unique dap molecules are unexceptional [14], and both molecules are in essentially extended conformations (mean absolute values of the N-C-C-C and C-C-C-C torsion angles = 177.6° and 174.7°, respectively).…”

Crystal Structure, Thermal Behavior and Vibrational Spectra of 4,4’Diamoniumdiphenylmethan Sulfate Hydrate

“…In fact, "pillared layer" materials and threedimensional frameworks are formed involving the sulfates ligands which pro-mote the formation of alternating organic and inorganic layers [4]. Not only the morphologies or the length of sulfate groupments can give this chemistry its important feature; but also the chemical identity of the organic group can profoundly influence the whole structure of these compounds [5]. Presently, various syntheses of organically cation-templated sulfates crystals were the subject of many investigations which have been of great benefit in various fields of sciences [6] [7] [8].…”
