An alloy of lanthanum and five nickel atoms complexes with these ions to form catalysts, while other metals are used with them in a namesake kind of fuel cell.  Nitriles, esters, and many other organic compounds can be reduced using an agent containing lithium, aluminum, and four of these ions.  For 10 points, name these ions that typically consist of one proton and two electrons.
