Platinum(II) bromide
Platinum bromide is the chemical compound with the formula PtBr2. This dark green powder is a common precursor to other platinum-bromide compounds. Like palladium chloride and palladium(II) bromide, it is a compound that dissolves only in coordinating solvents or in the presence of donor ligands.

Illustrative use
Transition metal carbene complex of platinum can be prepared by heating platinum bromide with the imidazolium salt NHC precursors, and sodium acetate in dimethyl sulfoxide.[1]
gollark: Though I guess you just need to reduce it to 10% or so to stop humans from being able to use it.
gollark: A complicating factor here is that whatever process you need to either remove the oxygen from earth or bind it in some chemical will probably run less efficiently as the oxygen content declines.
gollark: Wikipedia puts the mass of the atmosphere at 5.15e18 kg.
gollark: I was just thinking "hmm, big number".
gollark: You would also have to get rid of plankton and algae and random photosynthetic bacteria and whatnot.
