As As P Pt
PtAs2P is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PtAs2P clusters. Pt(1) is bonded in a 3-coordinate geometry to two equivalent As(1) and one P(1) atom. Both Pt(1)-As(1) bond lengths are 0.26 Å. The Pt(1)-P(1) bond length is 0.24 Å. As(1) is bonded in a 3-coordinate geometry to one Pt(1), one As(1), and one P(1) atom. The As(1)-As(1) bond length is 0.24 Å. The As(1)-P(1) bond length is 0.26 Å. P(1) is bonded in a 3-coordinate geometry to one Pt(1) and two equivalent As(1) atoms.
