KCl5 is Cyanogen Chloride-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KCl5 cluster. K(1) is bonded in a single-bond geometry to one Cl(1) and one Cl(5) atom. The K(1)-Cl(1) bond length is 2.60 Å. The K(1)-Cl(5) bond length is 0.01 Å. There are five inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a linear geometry to one K(1) and one Cl(2) atom. The Cl(1)-Cl(2) bond length is 1.13 Å. In the second Cl site, Cl(2) is bonded in a linear geometry to one Cl(1) and one Cl(3) atom. The Cl(2)-Cl(3) bond length is 1.39 Å. In the third Cl site, Cl(3) is bonded in a linear geometry to one Cl(2) and one Cl(4) atom. The Cl(3)-Cl(4) bond length is 1.24 Å. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Cl(3) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one K(1) atom.
