Hf Re Sn Pb
HfRePbSn crystallizes in the trigonal R3m space group. Hf(1) is bonded in a distorted body-centered cubic geometry to four equivalent Re(1), four equivalent Pb(1), and six equivalent Sn(1) atoms. There are three shorter (3.00 Å) and one longer (3.09 Å) Hf(1)-Re(1) bond length. There are three shorter (3.00 Å) and one longer (3.09 Å) Hf(1)-Pb(1) bond length. There are three shorter (3.42 Å) and three longer (3.57 Å) Hf(1)-Sn(1) bond lengths. Re(1) is bonded in a 14-coordinate geometry to four equivalent Hf(1), six equivalent Pb(1), and four equivalent Sn(1) atoms. There are three shorter (3.42 Å) and three longer (3.57 Å) Re(1)-Pb(1) bond lengths. There are three shorter (3.00 Å) and one longer (3.09 Å) Re(1)-Sn(1) bond length.
