The material structure described by EuOCl is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Eu(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and five equivalent Cl(1) atoms. O(1) is bonded to four equivalent Eu(1) atoms to form a mixture of corner and edge-sharing OEu4 tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1) atoms. is represented by the CIF card [CIF]
