KRe2Ag crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KRe2Ag clusters. K(1) is bonded in a 3-coordinate geometry to two equivalent Re(1) and one Ag(1) atom. Both K(1)-Re(1) bond lengths are 1.34 Å. The K(1)-Ag(1) bond length is 1.92 Å. Re(1) is bonded in a distorted single-bond geometry to one K(1) atom. Ag(1) is bonded in a single-bond geometry to one K(1) atom.
