The structure described by Zr9Mo4B crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 5-coordinate geometry to one Mo(2), three equivalent Mo(1), and one B(1) atom. In the second Zr site, Zr(2) is bonded in a 3-coordinate geometry to two equivalent Mo(1) and one B(1) atom. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 12-coordinate geometry to two equivalent Zr(2), six equivalent Zr(1), two equivalent Mo(1), and two equivalent Mo(2) atoms. In the second Mo site, Mo(2) is bonded to six equivalent Zr(1) and six equivalent Mo(1) atoms to form face-sharing MoZr6Mo6 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to three equivalent Zr(2) and six equivalent Zr(1) atoms. is represented by the CIF card [CIF]
