The 2D chemical structure image of Pyrophosphorous acid is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of Pyrophosphorous acid are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds.

The 3D chemical structure image of Pyrophosphorous acid is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model of Pyrophosphorous acid.
