BaCo2Pt crystallizes in the triclinic P1 space group. Ba(1) is bonded in a single-bond geometry to one Co(1), two equivalent Co(2), and one Pt(1) atom. The Ba(1)-Co(1) bond length is 2.51 Å. There is one shorter (2.69 Å) and one longer (3.15 Å) Ba(1)-Co(2) bond length. The Ba(1)-Pt(1) bond length is 0.76 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 1-coordinate geometry to one Ba(1) and two equivalent Co(2) atoms. There is one shorter (2.35 Å) and one longer (2.37 Å) Co(1)-Co(2) bond length. In the second Co site, Co(2) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Co(1), and two equivalent Pt(1) atoms. There is one shorter (2.51 Å) and one longer (2.99 Å) Co(2)-Pt(1) bond length. Pt(1) is bonded in a single-bond geometry to one Ba(1) and two equivalent Co(2) atoms.
