The material structure described by W2B5 is Tungsten boride-like structured and crystallizes in the trigonal R-3m space group. W(1) is bonded in a 10-coordinate geometry to four equivalent B(2) and six equivalent B(3) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded to six equivalent B(2) atoms to form distorted edge-sharing BB6 cuboctahedra. In the second B site, B(2) is bonded in a 10-coordinate geometry to four equivalent W(1), three equivalent B(1), and three equivalent B(2) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to six equivalent W(1) and three equivalent B(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
