Mn2PtZn crystallizes in the triclinic P1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 3-coordinate geometry to two equivalent Mn(2) and two equivalent Pt(1) atoms. There is one shorter (1.71 Å) and one longer (2.87 Å) Mn(1)-Mn(2) bond length. There is one shorter (2.19 Å) and one longer (2.45 Å) Mn(1)-Pt(1) bond length. In the second Mn site, Mn(2) is bonded in a 8-coordinate geometry to two equivalent Mn(1), two equivalent Mn(2), two equivalent Pt(1), and two equivalent Zn(1) atoms. Both Mn(2)-Mn(2) bond lengths are 2.85 Å. There is one shorter (2.52 Å) and one longer (2.75 Å) Mn(2)-Pt(1) bond length. There is one shorter (2.19 Å) and one longer (2.45 Å) Mn(2)-Zn(1) bond length. Pt(1) is bonded in a distorted single-bond geometry to two equivalent Mn(1), two equivalent Mn(2), and one Zn(1) atom. The Pt(1)-Zn(1) bond length is 0.91 Å. Zn(1) is bonded in a single-bond geometry to two equivalent Mn(2) and one Pt(1) atom.
