K K Ti Ag
K2TiAg is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2TiAg clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Ag(1) atom. The K(1)-Ag(1) bond length is 1.73 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Ti(1) atom. The K(2)-Ti(1) bond length is 1.04 Å. Ti(1) is bonded in a linear geometry to one K(2) and one Ag(1) atom. The Ti(1)-Ag(1) bond length is 0.69 Å. Ag(1) is bonded in a linear geometry to one K(1) and one Ti(1) atom.
