Ni H
NiH is Tungsten Carbide structured and crystallizes in the triclinic P1 space group. Ni(1) is bonded in a 1-coordinate geometry to five equivalent H(1) atoms. There are a spread of Ni(1)-H(1) bond distances ranging from 1.53-2.20 Å. H(1) is bonded in a 5-coordinate geometry to five equivalent Ni(1) atoms.
