Bond is located between carbons C1 and C2 as depicted in a picture below. Hexaphenylethane skeleton based derivative containing longest known C-C bond between atoms C1 and C2 with a length of 186.2 pm . Another notable compound with an extraordinary C-C bond length is tricyclobutabenzene, in which a bond length of 160 pm is reported.
In Gomberg's dimer, one C-C bond is rather long at 159.7 picometers. It is this bond that reversibly and readily breaks at room temperature in solution: [ 6 ] In the even more congested molecule hexakis(3,5-di- tert -butylphenyl)ethane , the bond dissociation energy to form the stabilized triarylmethyl radical is only 8 kcal/mol.
Atomic spacing refers to the distance between the nuclei of atoms in a material. This space is extremely large compared to the size of the atomic nucleus, and is related to the chemical bonds which bind atoms together. [1] In solid materials, the atomic spacing is described by the bond lengths of its atoms.
Bonded nuclei maintain an optimal distance (the bond distance) balancing attractive and repulsive effects explained quantitatively by quantum theory. [2] [3] The atoms in molecules, crystals, metals and other forms of matter are held together by chemical bonds, which determine the structure and properties of matter.
Molecular geometries can be specified in terms of 'bond lengths', 'bond angles' and 'torsional angles'. The bond length is defined to be the average distance between the nuclei of two atoms bonded together in any given molecule. A bond angle is the angle formed between three atoms across at least two bonds.
Here is the equilibrium bond energy and the bond distance. The Morse potential has been applied to studies of molecular vibrations and solids, [ 22 ] and also inspired the functional form of more accurate potentials such as the bond-order potentials.

Bond energy and bond-dissociation energy are measures of the binding energy between the atoms in a chemical bond. It is the energy required to disassemble a molecule into its constituent atoms. This energy appears as chemical energy , such as that released in chemical explosions , the burning of chemical fuel and biological processes.
