Ni Ni Pt Cl
PtNi2Cl crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PtNi2Cl clusters. Pt(1) is bonded in a single-bond geometry to one Cl(1) atom. The Pt(1)-Cl(1) bond length is 0.55 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted linear geometry to one Ni(2) and one Cl(1) atom. The Ni(1)-Ni(2) bond length is 0.99 Å. The Ni(1)-Cl(1) bond length is 2.75 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one Ni(1) atom. Cl(1) is bonded in a single-bond geometry to one Pt(1) and one Ni(1) atom.
