Tetra-n-propyl-ammonium chloride monohydrate
Summary
The crystal structure of a salt hydrate reveals non-interacting ions. Water molecules bridge chloride ions via hydrogen bonds, forming a unique planar ring structure.
Area of Science:
- Crystallography
- Solid-state chemistry
- Hydrogen bonding
Background:
- Understanding the structural characteristics of salt hydrates is crucial for predicting their physical and chemical properties.
- Investigating the role of water molecules in crystal lattice formation provides insights into intermolecular interactions.
Purpose of the Study:
- To elucidate the crystal structure of the title salt hydrate, C(12)H(28)N(+)·Cl(-)·H(2)O.
- To analyze the hydrogen bonding network and the arrangement of ions and water molecules within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular distances was performed.
Main Results:
- The crystal structure consists of discrete, non-interacting tetrabutylammonium cations (C(12)H(28)N(+)) and chloride anions (Cl(-)).
- Water molecules act as hydrogen bond donors and acceptors, linking two chloride ions through hydrogen bonds.
- A planar, eight-membered ring, {⋯H-O-H⋯Cl}(2), is formed around a center of inversion, involving the water molecule and two chloride ions.
Conclusions:
- The crystal structure is characterized by isolated ions and a specific hydrogen bonding motif involving water.
- The identified planar eight-membered ring represents a significant structural feature of this salt hydrate.

Ionic Compounds: Formulas and Nomenclature
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.
Nomenclature 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...
Structure 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...
Polyprotic Acids
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:
EDTA: Auxiliary Complexing Reagents
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...
Formation of Halohydrin from Alkenes
An alkene, such as propene, reacts with bromine in the presence of water to yield a halohydrin. Halohydrins contain a halogen and a hydroxyl group attached to adjacent carbons. When the halogen is bromine, it is called a bromohydrin, while a chlorohydrin has chlorine as the halogen.
