Re As Pb Pb
RePb2As crystallizes in the trigonal R3m space group. Re(1) is bonded in a 11-coordinate geometry to three equivalent Pb(2), four equivalent Pb(1), and four equivalent As(1) atoms. All Re(1)-Pb(2) bond lengths are 3.36 Å. There is one shorter (2.91 Å) and three longer (3.10 Å) Re(1)-Pb(1) bond lengths. There is one shorter (2.91 Å) and three longer (3.10 Å) Re(1)-As(1) bond lengths. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to four equivalent Re(1) and four equivalent Pb(2) atoms. There is one shorter (2.91 Å) and three longer (3.10 Å) Pb(1)-Pb(2) bond lengths. In the second Pb site, Pb(2) is bonded in a 10-coordinate geometry to three equivalent Re(1), four equivalent Pb(1), and three equivalent As(1) atoms. All Pb(2)-As(1) bond lengths are 2.93 Å. As(1) is bonded in a 7-coordinate geometry to four equivalent Re(1) and three equivalent Pb(2) atoms.
