DyB2C crystallizes in the tetragonal P4_2/mbc space group. Dy(1) is bonded in a 14-coordinate geometry to four equivalent B(1), six equivalent B(2), and four equivalent C(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted water-like geometry to four equivalent Dy(1) and two equivalent C(1) atoms. In the second B site, B(2) is bonded in a distorted single-bond geometry to six equivalent Dy(1) and one C(1) atom. C(1) is bonded in a 3-coordinate geometry to four equivalent Dy(1), one B(2), and two equivalent B(1) atoms.
DyB2C crystallizes in the tetragonal P4_2/mbc space group. Dy(1) is bonded in a 14-coordinate geometry to four equivalent B(1), six equivalent B(2), and four equivalent C(1) atoms. There are two shorter (2.64 Å) and two longer (2.65 Å) Dy(1)-B(1) bond lengths. There are a spread of Dy(1)-B(2) bond distances ranging from 2.76-2.78 Å. There are two shorter (2.60 Å) and two longer (2.61 Å) Dy(1)-C(1) bond lengths. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted water-like geometry to four equivalent Dy(1) and two equivalent C(1) atoms. There is one shorter (1.62 Å) and one longer (1.63 Å) B(1)-C(1) bond length. In the second B site, B(2) is bonded in a distorted single-bond geometry to six equivalent Dy(1) and one C(1) atom.
