Three-center two-electron bond — A three center two electron bond is an electron deficient chemical bond where three atoms share two electrons. The combination of three atomic orbitals form three molecular orbitals: one bonding, one non bonding, and one anti bonding. The two… … Wikipedia
Four-center two-electron bond — A four center two electron bond is a type of chemical bond in which four atoms share two electrons in bonding which is unusual because in ordinary chemical bonds two atoms share two electrons (2c 2e bonding). This type of bonding is postulated in … Wikipedia
