ZrPtZrSe crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one selanylidenezirconium molecule and one ZrPt cluster. In the ZrPt cluster, Zr(1) is bonded in a single-bond geometry to one Pt(1) atom. The Zr(1)-Pt(1) bond length is 0.48 Å. Pt(1) is bonded in a single-bond geometry to one Zr(1) atom.
