The structure described by BaNi9P5 crystallizes in the hexagonal P6_3/mmc space group. Ba(1) is bonded in a 24-coordinate geometry to six equivalent Ni(2), twelve equivalent Ni(1), and six equivalent P(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1), two equivalent P(1), and two equivalent P(2) atoms. In the second Ni site, Ni(2) is bonded in a 2-coordinate geometry to two equivalent Ba(1), two equivalent P(1), and two equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Ni(2), and four equivalent Ni(1) atoms. In the second P site, P(2) is bonded in a distorted q6 geometry to three equivalent Ni(2) and six equivalent Ni(1) atoms. is represented by the CIF file [CIF]
