Re Tc Sn Au
ReTcAuSn crystallizes in the trigonal R3m space group. Re(1) is bonded in a 7-coordinate geometry to one Tc(1), three equivalent Au(1), and three equivalent Sn(1) atoms. The Re(1)-Tc(1) bond length is 2.49 Å. All Re(1)-Au(1) bond lengths are 2.70 Å. All Re(1)-Sn(1) bond lengths are 2.70 Å. Tc(1) is bonded in a single-bond geometry to one Re(1), one Au(1), and three equivalent Sn(1) atoms. The Tc(1)-Au(1) bond length is 1.85 Å. All Tc(1)-Sn(1) bond lengths are 2.70 Å. Au(1) is bonded in a 1-coordinate geometry to three equivalent Re(1), one Tc(1), and four equivalent Sn(1) atoms. There is one shorter (2.49 Å) and three longer (2.91 Å) Au(1)-Sn(1) bond lengths. Sn(1) is bonded in a distorted single-bond geometry to three equivalent Re(1), three equivalent Tc(1), and four equivalent Au(1) atoms.
