Actually, that compound is lead (II) hydrogen phosphate, not lead (IV) hydrogen phosphate.

Notice that it contains the hydrogen phosphate anion, $HPO_4^(2-)$ , which carries a 2- charge.

This implies that the lead cation is in a +2 oxidation state, so you're actually dealing with the lead (II) cation, $Pb^(2+)$ .

As a result, the correct name for $PbHPO_4$ is lead (II) hydrogen phosphate.

Lead (IV) hydrogen phosphate will have the lead cation in a +4 oxidation state, so you'd be dealing with the lead (IV) ion, $Pb^(4+)$ .

As a result, lead (IV) hydrogen phosphate would be

$Pb_2(HPO_4)_4$ , or $Pb(HPO_4)_2$ .
