The compound described by EuCO3 crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Eu(1) and one C(1) atom. is represented by the CIF file [CIF]
