Ba Hf Co Pt
BaHfCoPt crystallizes in the trigonal R3m space group. Ba(1) is bonded in a 11-coordinate geometry to four equivalent Hf(1), four equivalent Co(1), and three equivalent Pt(1) atoms. There are three shorter (2.80 Å) and one longer (3.54 Å) Ba(1)-Hf(1) bond length. There are three shorter (2.80 Å) and one longer (3.54 Å) Ba(1)-Co(1) bond length. All Ba(1)-Pt(1) bond lengths are 2.88 Å. Hf(1) is bonded in a 11-coordinate geometry to four equivalent Ba(1), three equivalent Co(1), and four equivalent Pt(1) atoms. All Hf(1)-Co(1) bond lengths are 2.88 Å. There are three shorter (2.80 Å) and one longer (3.54 Å) Hf(1)-Pt(1) bond length. Co(1) is bonded in a single-bond geometry to four equivalent Ba(1), three equivalent Hf(1), and one Pt(1) atom. The Co(1)-Pt(1) bond length is 1.17 Å. Pt(1) is bonded in a single-bond geometry to three equivalent Ba(1), four equivalent Hf(1), and one Co(1) atom.
