The compound described by Zn3(PtSn)2 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a body-centered cubic geometry to two equivalent Zn(1) and six equivalent Sn(1) atoms. In the second Pt site, Pt(2) is bonded in a 11-coordinate geometry to three equivalent Zn(2), six equivalent Zn(1), and two equivalent Sn(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 11-coordinate geometry to one Pt(1), three equivalent Pt(2), one Zn(1), three equivalent Zn(2), and three equivalent Sn(1) atoms. In the second Zn site, Zn(2) is bonded in a trigonal planar geometry to three equivalent Pt(2) and six equivalent Zn(1) atoms. Sn(1) is bonded in a 7-coordinate geometry to one Pt(2), three equivalent Pt(1), and three equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
