Be Zn Pt Pt
BePt2Zn crystallizes in the triclinic P1 space group. Be(1) is bonded in a distorted single-bond geometry to one Pt(2), two equivalent Pt(1), and one Zn(1) atom. The Be(1)-Pt(2) bond length is 2.85 Å. There is one shorter (2.56 Å) and one longer (2.78 Å) Be(1)-Pt(1) bond length. The Be(1)-Zn(1) bond length is 0.66 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 5-coordinate geometry to two equivalent Be(1), one Pt(2), and two equivalent Zn(1) atoms. The Pt(1)-Pt(2) bond length is 1.21 Å. There is one shorter (2.85 Å) and one longer (3.05 Å) Pt(1)-Zn(1) bond length. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to one Be(1), one Pt(1), and two equivalent Zn(1) atoms. There is one shorter (2.56 Å) and one longer (2.78 Å) Pt(2)-Zn(1) bond length. Zn(1) is bonded in a distorted single-bond geometry to one Be(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
