The Supercomplexes in the Crista Membrane

The Supercomplexes in the Crista Membrane

The mitochondrial cristae membrane is the primary site for the oxidative phosphorylation (OXPHOS) process of energy conversion mediated through respiratory complexes I to V. These complexes have been widely studied for decades, and it has been proven that they form supramolecular structures called respiratory supercomplexes (SC). These higher-order complexes may be crucial in maintaining the biochemical structure and improving the physiological activity of the individual complexes while...

Ionic Crystal Structures

Ionic Crystal Structures

Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Resonance and Hybrid Structures

Resonance and Hybrid Structures

According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, the actual distribution of electrons is an average of that shown by the various Lewis structures.
Resonance Structures and Resonance Hybrids
The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N–O and N=O bonds.

Carbon Skeletons

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Valence Bond Theory

Valence Bond Theory

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Background:

Weakly bonded carbon dioxide (CO2) complexes are rare but offer significant advantages for carbon capture and CO2 utilization.
Current carbon capture technologies are energy-intensive due to the strong bonds requiring high regeneration energy.

Purpose of the Study:

To review and categorize diverse CO2 complexes with varying binding modes and reactivity.
To highlight the potential of novel CO2 chemistry for creating value-added products and reducing atmospheric CO2.

Main Methods:

Literature review of existing CO2 complexation strategies.
Categorization of complexes based on binding modes: inclusion, zwitterionic carbamates, carbamate salts, insertion products, Lewis acid-base adducts, and simple base-CO2 adducts.

Main Results:

Identified several classes of CO2 complexes, including those in porous materials, zwitterionic carbamates, carbamate salts, and Lewis acid-base adducts.
Highlighted simple base-CO2 adducts, particularly N-heterocyclic carbene adducts of CO2 (imidazol-2-carboxylates), as promising for weak CO2 binding.

Conclusions:

Weak CO2 binding is crucial for developing cost-effective carbon capture and enabling new CO2 conversion pathways.
Further research into novel CO2 complexes, especially simple base-CO2 adducts, could lead to significant advancements in carbon management and chemical synthesis.
