One possibility, for the lead(IV) salt, is Pb(C2O4)2.
The chemical formula for manganese II oxalate is MnC2O4.
The chemical formula for tin (II) oxalate is SnC2O4.
The formula of iron(III) oxalate is C6Fe2O12.
When tin bonds to the oxalate polyatomic ion, it does so as tin(II), so the compound is correctly written as tin(II) oxalate, or stannous oxalate, using the old-fashioned nomenclature. Its chemical formula is SnC2O4. Tin has 2 valence electrons, and the oxalate poly needs 2 electrons, so they combine is a 1:1 ratio.
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.

CrC2O4 is the chemical formula for chromium(II) oxalate, which is a chemical compound composed of chromium, carbon, and oxygen atoms. It is a green crystalline solid that is used in chemical research and as a reagent in chemical reactions.
The chemical formula of lead II chromate is PbCrO4.
The chemical formula for lead II sulfate is PbSO4.
The chemical formula for lead(II) arsenate is Pb3(AsO4)2.
The chemical formula of lead(II) phosphate is Pb3(PO4)2.
The chemical formula for lead salt depends on the specific salt. For instance, lead(II) acetate has the formula Pb(CH₃COO)₂, lead(II) chloride is PbCl₂, and lead(II) nitrate is Pb(NO₃)₂.
Lead acetate's chemical formula is Pb(CH3COO)2
