Sr Sr Zn Zn Pb Pb
SrZnPb crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to one Zn(1), one Zn(2), one Pb(1), and one Pb(2) atom. The Sr(1)-Zn(1) bond length is 3.10 Å. The Sr(1)-Zn(2) bond length is 2.69 Å. The Sr(1)-Pb(1) bond length is 3.10 Å. The Sr(1)-Pb(2) bond length is 2.69 Å. In the second Sr site, Sr(2) is bonded in a 1-coordinate geometry to one Zn(1), one Zn(2), one Pb(1), and one Pb(2) atom. The Sr(2)-Zn(1) bond length is 2.54 Å. The Sr(2)-Zn(2) bond length is 2.69 Å. The Sr(2)-Pb(1) bond length is 3.10 Å. The Sr(2)-Pb(2) bond length is 2.03 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), and three equivalent Pb(2) atoms. There are a spread of Zn(1)-Pb(2) bond distances ranging from 2.53-3.26 Å. In the second Zn site, Zn(2) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), and three equivalent Pb(1) atoms. There are a spread of Zn(2)-Pb(1) bond distances ranging from 2.53-3.26 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), and three equivalent Zn(2) atoms. In the second Pb site, Pb(2) is bonded in a 5-coordinate geometry to one Sr(1), one Sr(2), and three equivalent Zn(1) atoms.
