Dinickel boride explained
Dinickel boride is a chemical compound of nickel and boron with formula .[1] It is one of the borides of nickel.
The formula "" and the name "nickel boride" are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride. However, that product is not a well-defined compound, and its bulk formula is closer to (sic).[2]
Synthesis
Dinickel boride can be obtained (together with other nickel borides) by heating sodium borohydride with powdered nickel metal up to 670 °C in a closed vessel, so that the released hydrogen creates a pressure of up to 3.4 MPa. The main reactions can be summarized as
2 ↔ 2NaH +
2Ni + 2 + NaH ↔ + 3 + 2 + Nabut other reactions occur, yielding other borides.[3]
