Ni3Bi2S2 crystallizes in the cubic I2_13 space group. Ni(1) is bonded in a distorted linear geometry to four equivalent Bi(1) and two equivalent S(1) atoms. Bi(1) is bonded in a 7-coordinate geometry to six equivalent Ni(1) and one S(1) atom. S(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) and one Bi(1) atom.
Ni3Bi2S2 crystallizes in the cubic I2_13 space group. Ni(1) is bonded in a distorted linear geometry to four equivalent Bi(1) and two equivalent S(1) atoms. There are two shorter (2.72 Å) and two longer (2.89 Å) Ni(1)-Bi(1) bond lengths. Both Ni(1)-S(1) bond lengths are 2.16 Å. Bi(1) is bonded in a 7-coordinate geometry to six equivalent Ni(1) and one S(1) atom. The Bi(1)-S(1) bond length is 3.24 Å. S(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) and one Bi(1) atom.
