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 tin (II) oxalate is SnC2O4.
For example sodium oxalate has the chemical formula Na2C2O4.
The chemical formula for Calcium Oxalate is CaC2O4
Formula of ammonium oxalate monohydrate: (NH4)2C2O4.H2O
