Bis(butan-1-aminium) naphthalene-1,5-disulfonate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812018880
Abstract: In the title compound, 2C4H12N+·C10H6O6S22 , the anion lies on an inversion center, so the asymmetric unit contains half an anion and one cation which are linked by a strong N—H...O hydrogen bond. The crystal structure comprises discrete ions, which are linked into centrosymmetric R44(12) loops by N—H...O interactions.
Propanaminium p-toluenesulfonate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812019435
Abstract: In the crystal structure of the title salt, C3H10N+·C7H7O3S , N—H...O hydrogen bonds involving the ammonium groups of the cations and the sulfonate O atoms result in the formation of a three-dimensional network.
2-Hydroxypyridinium p-toluenesulfonate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812019873
Abstract: In the title molecular salt, C5H6NO+·C7H7O3S , the cations and anions are connected by N—H...O and O—H...O hydrogen bonds, forming [100] chains.
Bis(trimethylammonium) naphthalene-1,5-disulfonate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811052718
Abstract: The asymmetric unit of the title compound, 2C3H10N+·C10H6S2O62 , contains a half-anion, which is completed by inversion symmetry, and one cation. The cations and anions are associated via strong N—H...O(sulfonate) hydrogen-bonding interactions, forming cation–anion–cation groups. Secondary interactions such as C—H(ammonium)...O(sulfonate) and van der Waals interactions link the cations and anions together in a three-dimensional crystal structure, with zigzag rows of cations lying between layers of anions.
Bis(diisopropylammonium) naphthalene-1,5-disulfonate
Yu Jin
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811043492
Abstract: In the title compound, 2C6H16N+·C10H6O6S22 , the cations and anions are associated via N—H...O and C—H...O hydrogen-bonding interactions.
Bis(2-hydroxyethanaminium) terephthalate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812000293
Abstract: The asymmetric unit of the title salt, 2C2H8NO+·C8H4O42 , comprises one crystallographically independent 2-hydroxyethanaminium cation and one half terephthalate anion. In the crystal, hydrogen bonds involving the hydroxy and ammonium groups of the cations and the carboxylate O atoms of the terephthalate anions result in the formation of a three-dimensional network structure.
2-[(2-Hydroxyethyl)azaniumyl]ethanaminium oxalate monohydrate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811056157
Abstract: In the title hydrated molecular salt, C4H14N2O2+·C2O42 ·H2O, the oxalate dianion is almost planar (r.m.s. deviation = 0.020 ). In the crystal, the components are linked by N—H...O(water), N—H...O(oxalate) O—H(ammonium)...O(oxalate), O—H(water)...O(oxalate) and O—H(water)...O(ammonium) hydrogen bonds, thereby forming a complex three-dimensional packing motif.
Bis(3-hydroxypropanaminium) naphthalene-1,5-disulfonate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811053141
Abstract: In the title molecular salt, 2C3H10NO+·C10H6O6S22 , the cations and anions are associated via N—H...O and O—H...O hydrogen-bonding interactions, giving rise to a three-dimensional structure with zigzag rows of cations lying between rows of anions. The asymmetric unit contains one cation and one half-anion, which is related to the remainder of the molecule by an inversion center.
Tetraaquabis(2-methyl-1H-imidazole-κN3)cobalt(II) naphthalene-1,5-disulfonate
Yu Jin
Acta Crystallographica Section E , 2011, DOI: 10.1107/s160053681104548x
Abstract: In the title complex, [Co(C4H6N2)2(H2O)4](C10H6O6S2), the cation and anion both reside on crystallographic inversion centers, such that the asymmetric unit comprises one half cation and one half anion. The central CoII ion is coordinated by four water molecules and two 2-methylimidazole ligands, resulting in a trans-octahedral coordination geometry. The existence of strong N—H...O and O—H...O hydrogen-bonding interactions gives rise to a three-dimensional structure.
Methylammonium tetrafluoridoborate 18-crown-6 clathrate
Yu Jin
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811054432
Abstract: In the title compound, CH3NH3+·BF4 ·C12H24O6, the methylammonium cation makes three N—H...O hydrogen bonds to the 18-crown-6 molecule. The –NH3+ and –CH3 groups of the cation adopt a staggered conformation. The F atoms of the tetrafluoridoborate anion are disordered over two sets of sites in a 0.519 (11):0.481 (11) ratio. Weak C—H...F interactions occur in the crystal, which possibly correlate with the anion disorder.
