The structure described by (PtCr)2C crystallizes in the tetragonal P4/mmm space group. The structure consists of one 02329_fluka atom inside a PtCr framework. In the PtCr framework, Cr(1) is bonded in a linear geometry to two equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Cr(1) and two equivalent Pt(2) atoms to form distorted corner-sharing PtCr4Pt2 octahedra. The corner-sharing octahedra are not tilted. In the second Pt site, Pt(2) is bonded in a linear geometry to two equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
