Be Ni Pt Pt
BePt2Ni crystallizes in the triclinic P1 space group. Be(1) is bonded in a distorted single-bond geometry to one Pt(1), one Pt(2), and one Ni(1) atom. The Be(1)-Pt(1) bond length is 2.29 Å. The Be(1)-Pt(2) bond length is 2.64 Å. The Be(1)-Ni(1) bond length is 1.05 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to one Be(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 1.25 Å. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to one Be(1), one Pt(1), and two equivalent Ni(1) atoms. There is one shorter (2.29 Å) and one longer (2.64 Å) Pt(2)-Ni(1) bond length. Ni(1) is bonded in a distorted single-bond geometry to one Be(1) and two equivalent Pt(2) atoms.
