Hydrogen Bonds

Hydrogen Bonds

A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...

Hydrogen Bonds

Hydrogen BondsHydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.Hydrogen Bonds Control the World!Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are...

Covalent Bonding and Lewis Structures

Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons.

Introduction to Chemical Bonds

Introduction to Chemical Bonds

Chemical Bonds
The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms. The innermost electron shell has a maximum capacity of two electrons, but the next two electron shells can each have a maximum of eight electrons. This is known as the octet rule, which states that, with the exception of the innermost shell, atoms are most stable energetically when they have eight electrons in their valence shell, the...

Background:

Single-molecule conducting-bridge configurations are crucial in molecular electronics.
Conductance histograms are used to identify stable molecular junctions.
Previous studies identified Pt-H2-Pt bridges near 1G0 conductance.

Purpose of the Study:

To identify the origin of an uncharacterized low-conductance peak in Pt-H2 systems.
To elucidate the structure of novel molecular conducting bridges.

Main Methods:

Conductance measurements at cryogenic temperatures.
Analysis of conductance histograms.
Theoretical modeling of molecular junctions.

Main Results:

A previously unidentified low-conductance peak was observed in the conductance histogram.
This peak is attributed to a hydrogen-decorated platinum chain.
The platinum chain is in contact with the single hydrogen-molecule bridge.

Conclusions:

The study characterizes a new type of molecular conducting bridge.
This finding expands the understanding of hydrogen-metal interactions at the single-molecule level.
The results provide insights into the formation of complex molecular junctions.
