No, there is no coordinated covalent bond in H3PO4 (phosphoric acid). Coordinated covalent bonds, also known as dative covalent bonds or coordinate bonds, occur when both electrons in a covalent bond are provided by one atom, usually a Lewis base, while the other atom, the Lewis acid, accepts the electrons. These types of bonds are typically seen in coordination complexes or compounds involving transition metals.
In H3PO4, phosphoric acid, the central phosphorus atom forms covalent bonds with four oxygen atoms, resulting in a tetrahedral arrangement. Each oxygen atom shares one of its electrons with the phosphorus atom, forming a normal covalent bond. The phosphorus atom does not have an electron pair to donate to another atom, so it does not form any coordinated covalent bonds in this compound.
