Re Ag Ag Ge
ReAg2Ge crystallizes in the triclinic P1 space group. Re(1) is bonded in a 7-coordinate geometry to two equivalent Re(1), one Ag(1), two equivalent Ag(2), and two equivalent Ge(1) atoms. Both Re(1)-Re(1) bond lengths are 2.77 Å. The Re(1)-Ag(1) bond length is 2.12 Å. There is one shorter (2.27 Å) and one longer (3.13 Å) Re(1)-Ag(2) bond length. There is one shorter (2.25 Å) and one longer (2.67 Å) Re(1)-Ge(1) bond length. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Re(1) and one Ge(1) atom. The Ag(1)-Ge(1) bond length is 0.78 Å. In the second Ag site, Ag(2) is bonded in a 1-coordinate geometry to two equivalent Re(1) atoms. Ge(1) is bonded in a single-bond geometry to two equivalent Re(1) and one Ag(1) atom.
