The material structure described by Ho2OsC2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to two equivalent C(1) and three equivalent C(2) atoms to form a mixture of distorted corner and edge-sharing HoC5 square pyramids. In the second Ho site, Ho(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent C(1) and two equivalent C(2) atoms. Os(1) is bonded in a 3-coordinate geometry to one C(2) and two equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent Ho(1), two equivalent Ho(2), and two equivalent Os(1) atoms to form CHo4Os2 octahedra that share corners with two equivalent C(1)Ho4Os2 octahedra, corners with two equivalent C(2)Ho5Os octahedra, edges with two equivalent C(1)Ho4Os2 octahedra, and edges with five equivalent C(2)Ho5Os octahedra. The corner-sharing octahedral tilt angles range from 11-39°. In the second C site, C(2) is bonded to two equivalent Ho(2), three equivalent Ho(1), and one Os(1) atom to form CHo5Os octahedra that share corners with two equivalent C(1)Ho4Os2 octahedra, corners with four equivalent C(2)Ho5Os octahedra, edges with two equivalent C(2)Ho5Os octahedra, and edges with five equivalent C(1)Ho4Os2 octahedra. The corner-sharing octahedral tilt angles range from 2-39°. is represented by the Crystallographic Information File (CIF) [CIF]
