The corner-sharing octahedral tilt angles are 4°. There are three inequivalent O sites. In the first O site, O(2) is bonded to one Sr(1), three equivalent La(2), one Fe(1), and one Cu(1) atom to form a mixture of distorted face, corner, and edge-sharing OSrLa3FeCu octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
