A covalent bond formed through side-on overlap of compatible atomic orbitals, with a nodal plane containing the internuclear axis.
A delocalized pi system made from three compatible p orbitals and four electrons. In the simple orbital construction the bonding and nonbonding combinations are occupied and the antibonding combination is empty.

A pi bond (π bond) is a type of covalent bond that occurs when two atomic orbitals overlap in such a way that there is a region of electron density above and below the axis connecting the two nuclei of the bonding atoms. Pi bonds are typically formed between p orbitals that are aligned parallel to each other. Pi bonds usually occur in conjunction with sigma bonds (σ bonds).
