The crystal structure described by W2B5 is Tungsten boride structured and crystallizes in the hexagonal P6_3/mmc space group. W(1) is bonded in a 10-coordinate geometry to three equivalent B(3), three equivalent B(4), and four equivalent B(1) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 10-coordinate geometry to four equivalent W(1), three equivalent B(1), and three equivalent B(2) atoms. In the second B site, B(2) is bonded to six equivalent B(1) atoms to form distorted edge-sharing BB6 cuboctahedra. In the third B site, B(3) is bonded in a 9-coordinate geometry to six equivalent W(1) and three equivalent B(4) atoms. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to six equivalent W(1) and three equivalent B(3) atoms. is represented by the CIF file [CIF]
