Copper - Wikipedia
Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation).A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings  and the

Anion Substitution in Ca(BH4)2−CaI2: Synthesis, Structure …
2011/3/29· The substitution of the complex borohydride anion BH 4 − in calcium borohydride by the larger iodide anion I − is explored in order to tailor the hydrogen storage properties. Three new compounds are identified in the Ca(BH 4) 2 −CaI 2 system and are structurally characterized using the Rietveld method and synchrotron radiation powder X-ray diffraction (SR-PXD) data.
