Na Zn Pt Pt
NaPt2Zn is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NaPt2Zn clusters. Na(1) is bonded in a distorted single-bond geometry to two equivalent Pt(1) and one Zn(1) atom. Both Na(1)-Pt(1) bond lengths are 0.27 Å. The Na(1)-Zn(1) bond length is 0.12 Å. Pt(1) is bonded in a 3-coordinate geometry to one Na(1), one Pt(1), and one Zn(1) atom. The Pt(1)-Pt(1) bond length is 0.12 Å. The Pt(1)-Zn(1) bond length is 0.27 Å. Zn(1) is bonded in a single-bond geometry to one Na(1) and two equivalent Pt(1) atoms.
