FeCu3 is Tungsten-derived structured and crystallizes in the orthorhombic Cmmm space group. Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1) and four equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to two equivalent Fe(1), two equivalent Cu(2), and four equivalent Cu(1) atoms. In the second Cu site, Cu(2) is bonded in a distorted body-centered cubic geometry to four equivalent Cu(1) and four equivalent Cu(2) atoms.
FeCu3 is Tungsten-derived structured and crystallizes in the orthorhombic Cmmm space group. Fe(1) is bonded in a distorted body-centered cubic geometry to four equivalent Fe(1) and four equivalent Cu(1) atoms. All Fe(1)-Fe(1) bond lengths are 2.48 Å. All Fe(1)-Cu(1) bond lengths are 2.52 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to two equivalent Fe(1), two equivalent Cu(2), and four equivalent Cu(1) atoms. Both Cu(1)-Cu(2) bond lengths are 2.51 Å. All Cu(1)-Cu(1) bond lengths are 2.48 Å. In the second Cu site, Cu(2) is bonded in a distorted body-centered cubic geometry to four equivalent Cu(1) and four equivalent Cu(2) atoms. All Cu(2)-Cu(2) bond lengths are 2.48 Å.
