The compound described by HoAsSe crystallizes in the orthorhombic Pnma space group. Ho(1) is bonded in a 9-coordinate geometry to four equivalent As(1) and five equivalent Se(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent As(1) atoms. Se(1) is bonded to five equivalent Ho(1) atoms to form a mixture of distorted corner and edge-sharing SeHo5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
