SrNbNi2 crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 2-coordinate geometry to one Ni(2) and four equivalent Ni(1) atoms. The Sr(1)-Ni(2) bond length is 2.59 Å. There are a spread of Sr(1)-Ni(1) bond distances ranging from 2.45-3.39 Å. Nb(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are a spread of Nb(1)-Ni(2) bond distances ranging from 2.28-3.05 Å. There are a spread of Nb(1)-Ni(1) bond distances ranging from 2.57-3.16 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Nb(1) atoms. In the second Ni site, Ni(2) is bonded in a 2-coordinate geometry to one Sr(1) and three equivalent Nb(1) atoms.
