The crystal structure described by UReB4 crystallizes in the orthorhombic Pbam space group. U(1) is bonded in a 18-coordinate geometry to four equivalent Re(1), two equivalent B(4), four equivalent B(1), four equivalent B(2), and four equivalent B(3) atoms. Re(1) is bonded in a 15-coordinate geometry to four equivalent U(1), one Re(1), two equivalent B(1), two equivalent B(2), two equivalent B(3), and four equivalent B(4) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Re(1), one B(4), and two equivalent B(2) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Re(1), one B(3), and two equivalent B(1) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to four equivalent U(1), two equivalent Re(1), one B(2), one B(3), and one B(4) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent U(1), four equivalent Re(1), one B(1), one B(3), and one B(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
