Pi (p-p) and Pi (p-d) bonding

p\pi-p\pi\ Bonding

When one p-orbital of one atom contains one electron and the other atom also has one electron in the p orbirtal , both perpendiculat to the plane of the molecule  then the type of bond formed is known as ppi-ppi bonding.  

 

p\pi-d\pi\ Bonding

When one p-orbital of one atom contains one electron and the other atom also has one electron then the type of bond formed is known as p\pi-p\pi bonding. In other words, p\pi-d\pi bond is formed when p orbital of one atom and d orbital of another atom overlap laterally.

For example, PO43- has a p\pi-d\pi bonding because the lateral overlap of p-orbital of oxygen atom with d-orbital of sulphur atom occurs.
