The structure described by La(Ho2C5)2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 10-coordinate geometry to one C(3), two equivalent C(1), two equivalent C(2), two equivalent C(4), and three equivalent C(5) atoms. In the second Ho site, Ho(2) is bonded in a 10-coordinate geometry to one C(1), two equivalent C(4), three equivalent C(2), and four equivalent C(3) atoms. La(1) is bonded in a distorted q4 geometry to two equivalent C(4), four equivalent C(1), and four equivalent C(5) atoms. There are five inequivalent C sites. In the first C site, C(1) is bonded to one Ho(2), two equivalent Ho(1), two equivalent La(1), and one C(4) atom to form a mixture of distorted corner and edge-sharing CLa2Ho3C octahedra. The corner-sharing octahedral tilt angles range from 0-81°. In the second C site, C(2) is bonded in a 6-coordinate geometry to two equivalent Ho(1), three equivalent Ho(2), and one C(3) atom. In the third C site, C(3) is bonded in a 6-coordinate geometry to one Ho(1), four equivalent Ho(2), and one C(2) atom. In the fourth C site, C(4) is bonded in a 6-coordinate geometry to two equivalent Ho(1), two equivalent Ho(2), one La(1), and one C(1) atom. In the fifth C site, C(5) is bonded in a 6-coordinate geometry to three equivalent Ho(1), two equivalent La(1), and one C(5) atom. is represented by the Crystallographic Information File (CIF) [CIF]
