EuTiO3Cl crystallizes in the monoclinic C2/m space group. Eu(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(1), and four equivalent Cl(1) atoms. Ti(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Eu(1) and one Ti(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Ti(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Eu(1) and three equivalent Ti(1) atoms. Cl(1) is bonded to four equivalent Eu(1) atoms to form a mixture of edge and corner-sharing ClEu4 tetrahedra.
