Li Cr Cr Cr Cr Pt
LiCr4Pt crystallizes in the trigonal R3m space group. Li(1) is bonded in a single-bond geometry to three equivalent Cr(1) and one Pt(1) atom. All Li(1)-Cr(1) bond lengths are 2.00 Å. The Li(1)-Pt(1) bond length is 0.39 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to one Li(1), two equivalent Cr(1), and three equivalent Cr(2) atoms. Both Cr(1)-Cr(1) bond lengths are 1.32 Å. There is one shorter (2.29 Å) and two longer (2.99 Å) Cr(1)-Cr(2) bond lengths. In the second Cr site, Cr(2) is bonded in a 12-coordinate geometry to nine equivalent Cr(1) and three equivalent Pt(1) atoms. All Cr(2)-Pt(1) bond lengths are 3.12 Å. Pt(1) is bonded in a single-bond geometry to one Li(1) and three equivalent Cr(2) atoms.
