The structure described by YCo4B crystallizes in the hexagonal P-6m2 space group. Y(1) is bonded in a 18-coordinate geometry to three equivalent Co(2), twelve equivalent Co(1), and three equivalent B(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 12-coordinate geometry to four equivalent Y(1), two equivalent Co(2), four equivalent Co(1), and two equivalent B(1) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Co(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Co(1) atoms. is represented by the CIF file [CIF]
