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 $p \pi-p \pi$ 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.
