Fe Co Co Co Co Pt
FeCo4Pt crystallizes in the trigonal R3m space group. Fe(1) is bonded in a single-bond geometry to three equivalent Co(2) and one Pt(1) atom. All Fe(1)-Co(2) bond lengths are 3.23 Å. The Fe(1)-Pt(1) bond length is 0.29 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 3-coordinate geometry to two equivalent Co(1), three equivalent Co(2), and one Pt(1) atom. Both Co(1)-Co(1) bond lengths are 1.60 Å. There are two shorter (2.68 Å) and one longer (2.77 Å) Co(1)-Co(2) bond length. The Co(1)-Pt(1) bond length is 1.87 Å. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to three equivalent Fe(1) and nine equivalent Co(1) atoms. Pt(1) is bonded in a single-bond geometry to one Fe(1) and three equivalent Co(1) atoms.
