چکیده
The crystal structure of the title compound, C(7)H(8)NO(+)·HSO(4) (-), consists of O-H⋯Ohydrogen-bonded extended chains of hydrogen sulfate anions. Each hydrogen sulfate anion is furthermore connected to one 4-acetyl-pyridinium cation via a hydrogen bond of the N-H⋯O type.

The title compound, (C(7)H(8)NO)(6)[Sb(4)Cl(18)], contains centrosymmetric hexa-anions built up from four vertex-sharing alternating SbCl(5) square-based pyramids and highly distorted SbCl(6) octa-hedra when long (<3.2 Å) 'secondary' Sb-Cl inter-actions are taken into account. The inter-polyhedral Sb-Cl bonds define a square-shape. In the crystal, the components are linked by N-H⋯Cl, C-H⋯Cl and...
متن کاملComparison of Catalytic Effect of Alkali and Alkaline Earth Metals Hydrogen Sulfate: As the Promoter for an Efficient Synthesis of 3,4-Dihydropyrimidin-2(1H)-ones under Solvent-Free Conditions
Alkali and alkaline earth metals hydrogen sulfate catalyzed the one-pot three component condensation reactions of aldehydes, 1,3-dicarbonyl compounds and urea or thiourea under solvent-free conditions leading to 3,4-dihydropyrimidin-2(1H)-ones in high yields at 80 °C. Our results showed that Biginelli reaction not only is pH dependent, but the cation of catalyst plays an importan...

In the crystal structure of the title salt, 3C(5)H(6)NO(+)·HSO(4) (-)·SO(4) (2-)·H(2)O, the hydrogen sulfate ion is linked to the sulfate ion by an O-H⋯O hydrogen bond. The hydrogen sulfate-sulfate anion is a hydrogen-bond acceptor for the three independent cations and the uncoordinated water mol-ecule, the hydrogen-bonding inter-actions giving rise to a three-dimensional hydrogen-bonded networ...
