HoAsSe is Matlockite structured and 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 edge and corner-sharing SeHo5 trigonal bipyramids.
HoAsSe is Matlockite structured and 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. There are a spread of Ho(1)-As(1) bond distances ranging from 3.06-3.17 Å. There are a spread of Ho(1)-Se(1) bond distances ranging from 2.89-3.03 Å. As(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent As(1) atoms. There are two shorter (2.60 Å) and two longer (2.94 Å) As(1)-As(1) bond lengths. Se(1) is bonded to five equivalent Ho(1) atoms to form a mixture of distorted edge and corner-sharing SeHo5 trigonal bipyramids.
