Re Re Re Re Sn Sn
Re2Sn crystallizes in the triclinic P1 space group. There are four inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to one Re(2), one Re(4), one Sn(1), and one Sn(2) atom. The Re(1)-Re(2) bond length is 1.78 Å. The Re(1)-Re(4) bond length is 1.37 Å. The Re(1)-Sn(1) bond length is 2.24 Å. The Re(1)-Sn(2) bond length is 1.64 Å. In the second Re site, Re(2) is bonded in a 5-coordinate geometry to one Re(1), one Re(3), one Re(4), one Sn(1), and one Sn(2) atom. The Re(2)-Re(3) bond length is 2.42 Å. The Re(2)-Re(4) bond length is 2.24 Å. The Re(2)-Sn(1) bond length is 2.24 Å. The Re(2)-Sn(2) bond length is 2.42 Å. In the third Re site, Re(3) is bonded in a distorted single-bond geometry to one Re(2), one Sn(2), and three equivalent Sn(1) atoms. The Re(3)-Sn(2) bond length is 1.78 Å. There are a spread of Re(3)-Sn(1) bond distances ranging from 2.63-2.84 Å. In the fourth Re site, Re(4) is bonded in a distorted L-shaped geometry to one Re(1), one Re(2), and one Sn(1) atom. The Re(4)-Sn(1) bond length is 1.78 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to one Re(1), one Re(2), one Re(4), and three equivalent Re(3) atoms. In the second Sn site, Sn(2) is bonded in a distorted L-shaped geometry to one Re(1), one Re(2), and one Re(3) atom.
