The material structure described by Nd5Co19B6 crystallizes in the hexagonal P6/mmm space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to six equivalent Co(2) atoms. In the second Nd site, Nd(2) is bonded in a 18-coordinate geometry to six equivalent Co(3), six equivalent Co(4), and six equivalent B(1) atoms. In the third Nd site, Nd(3) is bonded in a 18-coordinate geometry to twelve equivalent Co(1) and six equivalent B(2) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted L-shaped geometry to two equivalent Nd(3), two equivalent Co(2), and two equivalent B(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1), three equivalent Co(1), and three equivalent Co(3) atoms. In the third Co site, Co(3) is bonded in a distorted L-shaped geometry to two equivalent Nd(2), two equivalent Co(2), and two equivalent B(1) atoms. In the fourth Co site, Co(4) is bonded in a distorted square co-planar geometry to four equivalent Nd(2) and four equivalent B(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 6-coordinate geometry to three equivalent Nd(2), three equivalent Co(3), and three equivalent Co(4) atoms. In the second B site, B(2) is bonded in a 6-coordinate geometry to three equivalent Nd(3) and six equivalent Co(1) atoms. is represented by the CIF card [CIF]
