Dianna,

Sodium hexachloroplatinate. Bostick and Sullivan sell it and have taken to
calling it "NA2". The key feature is that this salt has Pt in the +4
oxidation state which is the reason it is a contrast agent. It takes twice
the ferrous oxalate to reduce it to Pt metal (oxidation state 0).

See my other response to Sandy King.
