Mn Ni Pt Pt
MnPt2Ni crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnPt2Ni cluster. Mn(1) is bonded in a 3-coordinate geometry to one Pt(1), one Pt(2), and one Ni(1) atom. The Mn(1)-Pt(1) bond length is 0.55 Å. The Mn(1)-Pt(2) bond length is 0.36 Å. The Mn(1)-Ni(1) bond length is 0.36 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Mn(1) atom. In the second Pt site, Pt(2) is bonded in a single-bond geometry to one Mn(1) atom. Ni(1) is bonded in a single-bond geometry to one Mn(1) atom.
