Summary
This study details the crystal structure of a diammonium salt hydrate, revealing parallel stacking and inorganic-organic layering. An intricate hydrogen-bonding network connects crystal layers via sulfate anions and water molecules.
Area of Science:
- Crystallography
- Materials Science
- Supramolecular Chemistry
Background:
- Diammonium salts are known for their diverse crystal structures.
- Understanding crystal packing and hydrogen bonding is crucial for materials design.
- The specific compound C(7)H(20)N(2) (2+)·SO(4) (2-)·H(2)O has not been previously detailed.
Purpose of the Study:
- To elucidate the crystal structure of C(7)H(20)N(2) (2+)·SO(4) (2-)·H(2)O.
- To analyze the packing arrangement and hydrogen bonding interactions within the crystal lattice.
- To characterize the interplay between organic cations, sulfate anions, and water molecules.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the crystal structure.
- Analysis of crystallographic data focused on atomic positions, bond lengths, and angles.
- Intermolecular interactions, particularly hydrogen bonds, were identified and analyzed.
Main Results:
- The crystal structure features parallel stacking of the diammonium dication.
- Inorganic-organic layering, characteristic of n-alkyl-diammonium salts, was observed.
- A three-dimensional hydrogen-bonding network was identified, linking cation and anion layers through sulfate anions and water molecules.
Conclusions:
- The crystal structure of C(7)H(20)N(2) (2+)·SO(4) (2-)·H(2)O is characterized by specific packing motifs and extensive hydrogen bonding.
- The observed hydrogen bonding network plays a significant role in stabilizing the crystal lattice.

01:18Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.

01:19Diazonium Group Substitution: –OH and –H
Nitrous acid, a weak acid, is prepared in situ via the reaction of sodium nitrite with a strong acid under cold conditions. This nitrous acid prepared in situ reacts with primary arylamines to form arenediazonium salts. Such reactions are known as diazotization reactions. As shown in Figure 1, the formation of arenediazonium salts begins with the decomposition of nitrous acid in an acidic solution to give nitrosonium ions.
01:16Nomenclature of Carboxylic Acid Derivatives: Acid Halides, Esters, and Acid Anhydrides
Naming Acid Halides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.

02:42Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
01:19Structure of Amines
The hybridized nitrogen atom in amines possesses a lone pair of electrons and is bound to three substituents with a bond angle of around 108°, which is less than the tetrahedral angle of 109.5°. However, the C–N–H bond angle is slightly larger at 112°, with a carbon–nitrogen bond length of 147 pm. This carbon–nitrogen bond length of of amines is longer than the carbon–oxygen bond of alcohols (143 pm) but shorter than alkanes’ carbon–carbon bond (154 pm). These aspects are illustrated in Figure...
01:12Nomenclature of Secondary and Tertiary Amines
The secondary and tertiary amines are derivatives of ammonia, where two and three of its hydrogens are replaced by alkyl groups, respectively. Secondary and tertiary amines can be symmetrical with identical alkyl groups attached to the nitrogen atom or unsymmetrical when more than one type of alkyl group is present. The standard nomenclature of secondary and tertiary amines is similar to the names given to the primary amines. They are generally named alkylamines. As depicted in Figure 1, for...
