The material described by UWB4 crystallizes in the orthorhombic Cmmm space group. U(1) is bonded in a 18-coordinate geometry to four equivalent W(1), two equivalent B(3), four equivalent B(2), and eight equivalent B(1) atoms. W(1) is bonded in a 15-coordinate geometry to four equivalent U(1), one W(1), two equivalent B(2), four equivalent B(1), and four equivalent B(3) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent W(1), one B(1), one B(2), and one B(3) atom. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent W(1), one B(2), and two equivalent B(1) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to two equivalent U(1), four equivalent W(1), one B(3), and two equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
