La2Fe(SeO)2 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 3-coordinate geometry to five equivalent Se(1) and three equivalent O(1) atoms. Fe(1) is bonded in a distorted linear geometry to four equivalent Se(1) and two equivalent O(1) atoms. Se(1) is bonded in a 7-coordinate geometry to five equivalent La(1) and two equivalent Fe(1) atoms. O(1) is bonded to three equivalent La(1) and one Fe(1) atom to form a mixture of edge and corner-sharing OLa3Fe tetrahedra.
La2Fe(SeO)2 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a 3-coordinate geometry to five equivalent Se(1) and three equivalent O(1) atoms. There are a spread of La(1)-Se(1) bond distances ranging from 3.08-3.31 Å. There are two shorter (2.35 Å) and one longer (2.42 Å) La(1)-O(1) bond length. Fe(1) is bonded in a distorted linear geometry to four equivalent Se(1) and two equivalent O(1) atoms. All Fe(1)-Se(1) bond lengths are 2.82 Å. Both Fe(1)-O(1) bond lengths are 1.95 Å. Se(1) is bonded in a 7-coordinate geometry to five equivalent La(1) and two equivalent Fe(1) atoms. O(1) is bonded to three equivalent La(1) and one Fe(1) atom to form a mixture of edge and corner-sharing OLa3Fe tetrahedra.
