Sn(HOOCCOO)4
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.
The chemical formula for manganese II oxalate is MnC2O4.
Tin (II) Oxolate
One possibility, for the lead(IV) salt, is Pb(C2O4)2.
The formula of iron(III) oxalate is C6Fe2O12.

The chemical formula for tin(II) sulfite is SnSO3.
Sn(CLO3)2 Tin (II) has a positive 2 charge and Chlorate has a (-1) charge so you need to cholrates to one Tin.
Tin has two oxidation states (II and IV), and exhibits approximately equal stability in both its II and IV oxidation state. The chemical formula Tin (II) Iodide is SnI2. The chemical formula for Tin (IV) Iodide is SnI4.
The chemical formula for tin (II) phosphate is Sn3(PO4)2.
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
The chemical formula for Tin(II) Bromide is SnBr2.
The chemical formula for tin(II) sulfate is SnSO4.
