Cr P P P P Pt
CrPtP4 crystallizes in the trigonal R3m space group. Cr(1) is bonded in a 10-coordinate geometry to four equivalent Pt(1), three equivalent P(1), and three equivalent P(2) atoms. There is one shorter (2.56 Å) and three longer (3.19 Å) Cr(1)-Pt(1) bond lengths. All Cr(1)-P(1) bond lengths are 2.43 Å. All Cr(1)-P(2) bond lengths are 2.94 Å. Pt(1) is bonded in a 13-coordinate geometry to four equivalent Cr(1), three equivalent P(2), and six equivalent P(1) atoms. All Pt(1)-P(2) bond lengths are 2.92 Å. There are three shorter (2.52 Å) and three longer (2.75 Å) Pt(1)-P(1) bond lengths. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 3-coordinate geometry to one Cr(1), two equivalent Pt(1), one P(2), and two equivalent P(1) atoms. The P(1)-P(2) bond length is 2.15 Å. Both P(1)-P(1) bond lengths are 1.24 Å. In the second P site, P(2) is bonded in a 9-coordinate geometry to three equivalent Cr(1), three equivalent Pt(1), and three equivalent P(1) atoms.
