Pt3Zr is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded to six equivalent Pt(1) and six equivalent Pt(2) atoms to form a mixture of face and corner-sharing ZrPt12 cuboctahedra. In the second Zr site, Zr(2) is bonded to six equivalent Pt(1) and six equivalent Pt(2) atoms to form a mixture of face and corner-sharing ZrPt12 cuboctahedra. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a distorted see-saw-like geometry to two equivalent Zr(1) and two equivalent Zr(2) atoms. In the second Pt site, Pt(1) is bonded in a distorted square co-planar geometry to two equivalent Zr(1) and two equivalent Zr(2) atoms.
