SnC2O4
Sn(C2O4)2
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.
Manganese II oxalate is MnC2O4
The formula of iron(III) oxalate is C6Fe2O12.
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
Sn(CLO3)2 Tin (II) has a positive 2 charge and Chlorate has a (-1) charge so you need to cholrates to one Tin.

SnF2
The chemical formula for tin sulphide is SnS
Tin (II) cyanide has the formula Sn(CN)2.
There are two such tin oxides: Tin (II) oxide with formula SnO and tin (IV) dioxide, with formula SnO2.
The formula is Sn3(PO4)2.
The chemical formula for tin (IV) sulfide is SnS2.The chemical formula for tin (II) sulfide is SnS.
