EuCuO3 crystallizes in the monoclinic C2/c space group. Eu(1) is bonded in a 8-coordinate geometry to one O(2), three equivalent O(3), and four equivalent O(1) atoms. Cu(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Eu(1) and one Cu(1) atom. In the second O site, O(2) is bonded in a T-shaped geometry to one Eu(1) and two equivalent Cu(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Eu(1) and one Cu(1) atom.
EuCuO3 crystallizes in the monoclinic C2/c space group. Eu(1) is bonded in a 8-coordinate geometry to one O(2), three equivalent O(3), and four equivalent O(1) atoms. The Eu(1)-O(2) bond length is 2.38 Å. There are a spread of Eu(1)-O(3) bond distances ranging from 2.31-2.73 Å. There are a spread of Eu(1)-O(1) bond distances ranging from 2.39-2.97 Å. Cu(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), and two equivalent O(2) atoms. The Cu(1)-O(1) bond length is 1.87 Å. The Cu(1)-O(3) bond length is 1.84 Å. There is one shorter (1.84 Å) and one longer (1.85 Å) Cu(1)-O(2) bond length. There are three inequivalent O sites.
