A three-center two-electron (3c–2e) bond is an electron-deficient chemical bond where three atoms share two electrons. The combination of three atomic...

The 3-center 4-electron (3c–4e) bond is a model used to explain bonding in certain hypervalent molecules such as tetratomic and hexatomic interhalogen...

metal-to-metal bonding, agostic interactions, bent bonds, three-center two-electron bonds and three-center four-electron bonds. The term covalent bond dates from...

are two types of three-center bonds: Three-center two-electron bond, found in electron-deficient compounds such as boranes Three-center four-electron bond...

A 4-center 2-electron (4c–2e) bond is a type of chemical bond in which four atoms share two electrons in bonding, with a net bond order of 1⁄2. This type...

share two electrons. Other types include the double bond, the triple bond, one- and three-electron bonds, the three-center two-electron bond and three-center...

an empty d-orbital of the transition metal, resulting in a three-center two-electron bond. It is a special case of a C–H sigma complex. Historically,...

heavier Group 2 elements, beryllium hydride is covalently bonded (three-center two-electron bond). Unlike the other group 2 metals, beryllium does not react...

because its two electrons are the only valence electrons in the system. It is also the simplest example of a three-center two-electron bond system. H+3...

chemical bond, the electrons' locations are determined by the molecule as a whole, so the atomic orbitals combine to form molecular orbitals. The electrons from...
