The material described by HoMoB3 crystallizes in the monoclinic P2_1/m space group. Ho(1) is bonded in a 10-coordinate geometry to three equivalent B(2), three equivalent B(3), and four equivalent B(1) atoms. Mo(1) is bonded in a 9-coordinate geometry to three equivalent B(1), three equivalent B(2), and three 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 Ho(1), three equivalent Mo(1), and two equivalent B(1) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Mo(1), one B(3), and two equivalent B(2) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Mo(1), one B(2), and two equivalent B(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
