CaFePtCu crystallizes in the trigonal R3m space group. Ca(1) is bonded in a single-bond geometry to four equivalent Fe(1), one Pt(1), and three equivalent Cu(1) atoms. There is one shorter (2.77 Å) and three longer (2.83 Å) Ca(1)-Fe(1) bond lengths. The Ca(1)-Pt(1) bond length is 1.47 Å. All Ca(1)-Cu(1) bond lengths are 2.70 Å. Fe(1) is bonded in a 10-coordinate geometry to four equivalent Ca(1), three equivalent Pt(1), and three equivalent Cu(1) atoms. All Fe(1)-Pt(1) bond lengths are 2.70 Å. All Fe(1)-Cu(1) bond lengths are 2.70 Å. Pt(1) is bonded in a single-bond geometry to one Ca(1), three equivalent Fe(1), and four equivalent Cu(1) atoms.
