The material structure described by HoCO4 crystallizes in the orthorhombic P2_12_12_1 space group. Ho(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(4), and three equivalent O(3) atoms. C(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ho(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Ho(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ho(1) and one C(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Ho(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
