Re Ag Ag Ag Ag Ge
ReAg4Ge is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three ReAg4Ge clusters. Re(1) is bonded in a 3-coordinate geometry to three equivalent Ag(1) atoms. All Re(1)-Ag(1) bond lengths are 0.91 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 2-coordinate geometry to one Re(1), one Ag(2), and two equivalent Ag(1) atoms. The Ag(1)-Ag(2) bond length is 0.80 Å. Both Ag(1)-Ag(1) bond lengths are 0.46 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to three equivalent Ag(1) and one Ge(1) atom. The Ag(2)-Ge(1) bond length is 1.55 Å. Ge(1) is bonded in a single-bond geometry to one Ag(2) atom.
