Cr Cr Cr Cr Ge Pt
Cr4PtGe crystallizes in the trigonal R3m space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1), three equivalent Cr(2), one Pt(1), and one Ge(1) atom. Both Cr(1)-Cr(1) bond lengths are 1.33 Å. There is one shorter (2.31 Å) and two longer (3.03 Å) Cr(1)-Cr(2) bond lengths. The Cr(1)-Pt(1) bond length is 2.19 Å. The Cr(1)-Ge(1) bond length is 2.00 Å. In the second Cr site, Cr(2) is bonded in a 15-coordinate geometry to nine equivalent Cr(1), three equivalent Pt(1), and three equivalent Ge(1) atoms. All Cr(2)-Pt(1) bond lengths are 3.05 Å. All Cr(2)-Ge(1) bond lengths are 3.20 Å. Pt(1) is bonded in a single-bond geometry to three equivalent Cr(1), three equivalent Cr(2), and one Ge(1) atom. The Pt(1)-Ge(1) bond length is 1.02 Å. Ge(1) is bonded in a single-bond geometry to three equivalent Cr(1), three equivalent Cr(2), and one Pt(1) atom.
