Ho2Re2Si2C crystallizes in the monoclinic C2/m space group. Ho(1) is bonded in a 2-coordinate geometry to five equivalent Si(1) and two equivalent C(1) atoms. Re(1) is bonded in a single-bond geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 9-coordinate geometry to five equivalent Ho(1), three equivalent Re(1), and one Si(1) atom. C(1) is bonded to four equivalent Ho(1) and two equivalent Re(1) atoms to form edge-sharing CHo4Re2 octahedra.
Ho2Re2Si2C crystallizes in the monoclinic C2/m space group. Ho(1) is bonded in a 2-coordinate geometry to five equivalent Si(1) and two equivalent C(1) atoms. There are a spread of Ho(1)-Si(1) bond distances ranging from 3.01-3.14 Å. Both Ho(1)-C(1) bond lengths are 2.62 Å. Re(1) is bonded in a single-bond geometry to three equivalent Si(1) and one C(1) atom. There are two shorter (2.45 Å) and one longer (2.48 Å) Re(1)-Si(1) bond length. The Re(1)-C(1) bond length is 1.94 Å. Si(1) is bonded in a 9-coordinate geometry to five equivalent Ho(1), three equivalent Re(1), and one Si(1) atom. The Si(1)-Si(1) bond length is 2.53 Å. C(1) is bonded to four equivalent Ho(1) and two equivalent Re(1) atoms to form edge-sharing CHo4Re2 octahedra.
