The crystal structure described by LaCO4 crystallizes in the orthorhombic Pnma space group. La(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(3), and six equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent La(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent La(1) and one C(1) atom. In the third O site, O(3) is bonded in a water-like geometry to two equivalent La(1) atoms. is represented by the CIF file [CIF]
