CrPtAs2 crystallizes in the monoclinic Pm space group. Cr(1) is bonded in a single-bond geometry to one Pt(1) and four equivalent As(1) atoms. The Cr(1)-Pt(1) bond length is 0.82 Å. There are two shorter (2.88 Å) and two longer (3.11 Å) Cr(1)-As(1) bond lengths. Pt(1) is bonded in a single-bond geometry to one Cr(1) and four equivalent As(1) atoms. There are two shorter (2.88 Å) and two longer (3.11 Å) Pt(1)-As(1) bond lengths. As(1) is bonded in a 5-coordinate geometry to two equivalent Cr(1), two equivalent Pt(1), and one As(1) atom. The As(1)-As(1) bond length is 1.05 Å.
