The material described by Ni7Ga2Ge2 crystallizes in the hexagonal P-6m2 space group. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 14-coordinate geometry to one Ni(1), one Ni(2), three equivalent Ni(3), three equivalent Ni(4), three equivalent Ga(1), and three equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a 11-coordinate geometry to one Ni(1), one Ni(2), three equivalent Ni(3), three equivalent Ga(2), and three equivalent Ge(1) atoms. In the third Ni site, Ni(3) is bonded in a 11-coordinate geometry to three equivalent Ni(1), three equivalent Ni(2), one Ga(1), one Ga(2), and three equivalent Ge(1) atoms. In the fourth Ni site, Ni(4) is bonded in a 11-coordinate geometry to six equivalent Ni(1), three equivalent Ga(1), and two equivalent Ge(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Ni(3), three equivalent Ni(4), and six equivalent Ni(1) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to two equivalent Ni(3) and six equivalent Ni(2) atoms. Ge(1) is bonded in a 10-coordinate geometry to one Ni(4), three equivalent Ni(1), three equivalent Ni(2), and three equivalent Ni(3) atoms. is represented by the CIF card [CIF]
