K Zn Zn Pt
KPtZn2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KPtZn2 clusters. K(1) is bonded in a 2-coordinate geometry to two equivalent Zn(1) atoms. Both K(1)-Zn(1) bond lengths are 1.94 Å. Pt(1) is bonded in a 2-coordinate geometry to two equivalent Zn(1) atoms. Both Pt(1)-Zn(1) bond lengths are 1.94 Å. Zn(1) is bonded in a 2-coordinate geometry to one K(1) and one Pt(1) atom.
