K Re Ag Ag
KReAg2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KReAg2 cluster. K(1) is bonded in a 3-coordinate geometry to one Re(1), one Ag(1), and one Ag(2) atom. The K(1)-Re(1) bond length is 1.68 Å. The K(1)-Ag(1) bond length is 1.34 Å. The K(1)-Ag(2) bond length is 1.68 Å. Re(1) is bonded in a 2-coordinate geometry to one K(1) and one Ag(2) atom. The Re(1)-Ag(2) bond length is 0.84 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one K(1) atom. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to one K(1) and one Re(1) atom.
