The formula "Ni
2B" 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 Na
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
4 ↔ 2NaH + B
- 2Ni + 2B
6 + NaH ↔ Ni
2B + 3BH
3 + 2H
2 + Na
but other reactions occur, yielding other borides.
