Summary
The crystal structure reveals how organic cations and nitrate anions form infinite chains and planar layers through various hydrogen bonds. This detailed structural analysis enhances understanding of crystal packing in such compounds.
Area of Science:
- Crystallography and Molecular Structure
- Supramolecular Chemistry
Background:
- Understanding the three-dimensional arrangement of atoms in crystalline solids is fundamental to materials science.
- Hydrogen bonding plays a crucial role in dictating crystal packing and emergent properties.
Purpose of the Study:
- To elucidate the detailed crystal structure of the title compound, C(6)H(7)N(2)O(2) (+)·NO(3) (-).
- To identify and characterize the hydrogen bonding interactions present in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the atomic arrangement.
- Analysis of intermolecular interactions, specifically hydrogen bonds (C-H⋯O, N-H⋯O, O-H⋯O), was performed.
Main Results:
- The crystal structure consists of organic cations (C(6)H(7)N(2)O(2) (+)) and nitrate anions (NO(3) (-)).
- Cations are organized into infinite chains along the b axis via C-H⋯O hydrogen bonds.
- These chains assemble into infinite planar layers parallel to (001) through interactions with nitrate anions involving N-H⋯O, O-H⋯O, and C-H⋯O hydrogen bonds.
Conclusions:
- The study successfully characterized the supramolecular architecture of the title compound.
- The intricate network of hydrogen bonds dictates the formation of extended chain and layered structures.

01:29Amino Acid Biosynthetic Pathways
1.2K
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

01:18Amino Acid Catabolism
1.1K
Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...

Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

01:11ortho–para-Directing Activators: –CH3, –OH, –NH2, –OCH3
7.3K
All ortho–para directors, excluding halogens, are activating groups. These groups donate electrons to the ring, making the ring carbons electron-rich. Consequently, the reactivity of the aromatic ring towards electrophilic substitution increases. For instance, the nitration of anisole is about 10,000 times faster than the nitration of benzene. The electron-donating effect of the methoxy group in anisole activates the ortho and para positions on the ring and stabilizes the corresponding...

8.3K
The nitration of benzene is an example of an electrophilic aromatic substitution reaction. It involves the formation of a very powerful electrophile, the nitronium ion, which is linear in shape. The reaction occurs through the interaction of two strong acids, sulfuric and nitric acid.

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
