DySe crystallizes in the hexagonal P6_3mc space group. Dy(1) is bonded to four equivalent Se(1) atoms to form distorted corner-sharing DySe4 trigonal pyramids. Se(1) is bonded to four equivalent Dy(1) atoms to form distorted corner-sharing SeDy4 trigonal pyramids.
DySe crystallizes in the hexagonal P6_3mc space group. Dy(1) is bonded to four equivalent Se(1) atoms to form distorted corner-sharing DySe4 trigonal pyramids. There is one shorter (2.77 Å) and three longer (2.81 Å) Dy(1)-Se(1) bond lengths. Se(1) is bonded to four equivalent Dy(1) atoms to form distorted corner-sharing SeDy4 trigonal pyramids.
